Where to massage for plantar fasciitis
Plantar fasciitis is a common condition seen in clinics, often more frequent among women who wear high heels for extended periods on uneven surfaces, as this may increase the likelihood of developing the condition. Due to prolonged tension in the soles of the feet, coupled with extended periods of standing and walking, this phenomenon can easily occur. Once it happens, treatments such as heat application, physiotherapy, massage, and electric heating can help alleviate the symptoms. Methods like massage and heat application can stimulate increased local blood flow, expand blood vessels, and accelerate blood flow, effectively alleviating symptoms and thus easing the discomfort caused by plantar fasciitis. It is best to rest strictly in bed for this condition. When standing, the weight-bearing on the affected foot makes the pain more pronounced. Symptoms naturally alleviate when the fascia is relaxed during rest. Treatments such as physiotherapy and massage, as well as taking medications that promote blood circulation and relieve pain, are needed. The improvement is a prolonged process, but conditions are prone to recurrence. It is advisable to wear softer sports shoes more often, with softer, thicker insoles to reduce the frequency of outbreaks.
Can osteosarcoma be cured?
Osteosarcoma is a malignant tumor of the bone, commonly occurring in adolescents and young adults, primarily near the proximal end of the tibia, the distal ancient end, or near the proximal end of the humerus, most frequently seen at the end of the bone shaft. In the early stages, there are no symptoms, and once detected, it is usually in the middle to late stages. An X-ray examination can be used for diagnosis, often showing a Codman's triangle or a sunburst pattern. Osteosarcoma generally needs early detection and treatment. If a primary lesion is present, surgical treatment can be pursued, including procedures such as resection with inactivation and reimplantation or limb-sparing surgery with a prosthesis. Another option is amputation, followed by extensive chemotherapy. The likelihood of osteosarcoma spreading to the lungs is very high. In recent years, with early diagnostic physical examinations and the rapid development of chemotherapy, the five-year survival rate for osteosarcoma can reach 50%.
How should lumbar muscle strain be treated?
Lumbar muscle strain is a particularly common disease, such as strenuous exercise or long periods of heavy physical labor. For instance, farmers bending over, farming, hoeing, cutting grass, fertilizing, and spraying pesticides are all activities closely related to the movement of the lumbar muscles. The human body's muscles engage in 80% of activities, and their involvement in lumbar muscle strain is very common. It mainly manifests as swinging hammers, digging tree pits, bending over to lift heavy objects, and carrying heavy weights. Subsequently, pain and discomfort in the lumbar region occur. The next morning, upon waking, the symptoms may become more apparent. The lumbar area may feel stiff, akin to a plank, making getting out of bed difficult. Through physical examination and radiographic imaging, such as CT scans of the lumbar spine, the condition can generally be identified and confirmed. In such cases, strict bed rest is required, generally for at least ten days, during which symptoms gradually alleviate. During this period, treatments such as traction, physiotherapy, massage, and heating can help alleviate the symptoms. If necessary, blood-activating and pain-relieving medications may be taken. The condition is treatable, but it is advisable to avoid prolonged sitting in the future. When engaging in heavy labor, it is better to restrict the lumbar region by wearing a lumbar belt or engaging in lighter physical activities that do not overly exert the lumbar area. Regular care for the lumbar region is essential. Once there is damage to the lumbar region, recurrent episodes can affect the quality of normal life and work.
Can you exercise with lumbar muscle strain?
Lumbar muscle strain primarily arises from repetitive stretching of the back muscles due to work-related activities or intense physical exercise. This leads to a range of symptoms, such as stiffness in the lower back upon waking in the morning, reluctance to move, and symptomatic relief after some activity. It is advised to gently exercise the lower back to effectively alleviate symptoms, avoid strenuous exercise or prolonged bending and heavy physical labor. It's best to strictly rest on a firm mattress, perform warm-up activities for the lower back, and undergo appropriate physical therapy and massage. Consuming blood-activating and pain-relieving medications can also help. Typically, symptoms will gradually ease over 7-10 days. Although light activity for lumbar muscle strain is acceptable, engaging in exercise is not recommended. Rest is necessary, and a general rest period of about half a month will gradually reduce symptoms. Recurrences are common, so it is important to regularly care for your lower back by avoiding activities such as bending to lift heavy objects, carrying heavy loads, etc., as these can easily lead to repetitive strain injuries of the back muscles.
How to do cervical traction for cervical spondylosis?
Cervical traction therapy can restore the physiological curvature of the cervical spine to relieve the compression of nerves and blood vessels caused by cervical spondylosis. You can purchase a cervical traction device from a pharmaceutical company or pharmacy, as it is a ready-made product. Additionally, there is an integrated traction belt made from canvas, which grips the forehead, lower jaw, and the back of the head. The belt then folds into a triangle shape upwards, with a loop in the middle through which a rope is threaded. This rope can be hung from a beam or a traction frame. By holding the rope, you perform a neck traction exercise by pulling upwards. This vertical traction can alleviate the symptoms of cervical spondylosis. It is recommended to perform traction once or twice daily, ideally morning and evening, with each session lasting about 20 minutes. Typically, symptoms can be relieved in about seven to ten days, and this is quite beneficial for cervical spondylosis. Additionally, when sleeping, try to use a low pillow, and avoid prolonged periods of bending your head down or engaging in activities such as working at a desk, playing mahjong, reading, or using a computer. Generally, following these guidelines can help prevent the recurrence of cervical spondylosis.
Causes of tenosynovitis
The causes of tenosynovitis, simply put, the tendon sheath is a double-layered dense synovial tube that encases the tendons. It acts as a protective fluid sheath for the tendons, consisting of two layers enveloping the tendon. Between these two layers is a cavity filled with synovial fluid. The inner layer is closely attached to the tendon, while the outer layer lines the inside of the tendon fibrous sheath, jointly attaching to the bone. It primarily functions to stabilize, protect, and lubricate the tendons, preventing them from friction-induced damage and compression. Long periods of excessive friction can lead to damage in both the tendon and its sheath, leading to swelling and pain, which are the symptoms of tenosynovitis. For example, certain occupations such as bricklayers, carpenters, those who work extensively with computers, and chefs who frequently stir with spoons, as well as seamstresses in textile factories, are prone to developing tenosynovitis. There might be a link between this condition and occupational diseases. In such cases, applying heat can be helpful, and if the pain is particularly severe, enclosed treatments might be conducted. Additionally, taking drugs that promote blood circulation and relieve pain might be advisable. In severe cases, surgical treatment may be necessary. (The use of medications should be under the guidance of a doctor.)
Can sciatica patients walk?
Sciatica can be managed with activities like walking, brisk walking, or jogging. It is best to walk or even walk backwards. It is important to avoid sitting for long periods, bending over, or carrying heavy objects. When the spine is bent, it can increase the pressure on the intervertebral discs, potentially worsening the nucleus pulposus, rupturing the annulus fibrosus, and causing a series of symptoms related to nerve root compression. This compression can cause local swelling, which can press on the nerves to varying degrees. It is recommended to strictly rest on a hard bed, and generally, with about ten days to two weeks of warming up the lower back, recovery is usually achievable. Gradual relief and disappearance of symptoms can occur, and it is advisable to avoid sitting for long periods, bending, or carrying heavy loads. Moderate walking is suitable.
Difference between arthritis and rheumatoid arthritis
Arthritis is typically osteoarthritis, a chronic inflammation characterized primarily by degenerative changes in joint cartilage, followed by bone proliferation, making it a chronic disease. Early pathological changes include alterations in joint cartilage, such as subchondral bone extrusion, followed by changes in the muscles surrounding the periosteum and joint capsule. Early radiographic examinations can provide a definitive diagnosis. Its symptoms primarily manifest as pain. For rheumatoid arthritis, it generally presents as morning stiffness and joint swelling and pain more severe than in the surrounding area, which can essentially confirm a diagnosis. It usually affects large joints such as the knee, shoulder, or wrist joints, typically presenting as migratory pain. A definitive diagnosis can usually be made by testing for rheumatoid factor, with an anti-O level exceeding 500 units. Additionally, there may be a slight increase in white blood cells, accelerated erythrocyte sedimentation rate, and elevated C-reactive protein. Examination of the synovial fluid shows increased white blood cells and neutrophils. In such cases, using anti-rheumatic drugs might suffice, but it’s also crucial to ensure rest and local heat application. These two types of arthritis fundamentally differ.
Characteristics of Osteosarcoma
Osteosarcoma is a malignant tumor of the bone that primarily occurs in adolescents and young adults, commonly found at the metaphyseal ends of long bones. For example, it may occur at the distal end of the tibia, the distal end of the femur, or the metaphyseal end of the humerus. Clinically, the main symptom is pain, which is persistent and more noticeable at night, accompanied by a local mass, limited movement, increased local skin temperature, distended veins, and general symptoms such as weight loss and even cachexia. Some patients may experience pathological fractures. Often, there are no symptoms in the early stages, and by the time it is detected, it is usually in an intermediate or advanced stage. Radiographic examination typically shows a Codman's triangle or sunburst pattern. Early detection and treatment are crucial. The usual treatment choice is surgical, such as deactivation and reimplantation, or limb-salvage surgery with prosthetic implantation. Additionally, amputation followed by extensive chemotherapy is another option. With recent advances in chemotherapy, there has been significant improvement in life extension.
How long should one stay in bed with a rib fracture?
Rib fractures are mostly caused by trauma, such as direct or indirect force. Radiographic examination can basically confirm the diagnosis. A single rib fracture generally requires no intervention or special treatment, just immobilization is sufficient. However, strict bed rest is necessary. Typically, immobilization for about four weeks is needed until callus formation occurs. During this period, you should avoid deep breathing, heavy breathing, or coughing, and stay away from cooking fumes and smokers. Such irritative coughing might cause pain. A rib fracture will likely also result in intercostal neuralgia, which can be very troublesome and prolong the pain. However, fractures generally fully heal within eight to ten months. They can gradually heal without issues, but it is best to rest in bed for a month.
