How to diagnose tenosynovitis?
Tendinitis refers to the condition where the tendons and their sheaths, due to excessive flexing and extending activities, develop adhesion and exudation between each other, leading to a painful aseptic inflammatory response. Generally, when tendinitis occurs, there is restricted movement in flexing and extending, as well as localized pain symptoms. Moreover, tenderness is also pronounced in areas where tendinitis symptoms are evident. Therefore, the diagnosis of tendinitis can be made through symptoms and examination, and when necessary, ultrasound and MRI can be used to reflect local swelling and inflammatory responses.
Can sciatica patients run?
The pain of the sciatic nerve is generally caused by degeneration of the intervertebral disc. The nucleus pulposus protrudes through the rupture of the fibrous ring of the degenerated disc, compressing the nerve root, which leads to symptoms such as sciatic nerve pain, numbness, and even restricted movement when walking. The intervertebral disc serves to absorb shocks and cushion the pressure on the lower back. During running, the load on the lower back increases, which could potentially exacerbate the symptoms of sciatic nerve pain. Therefore, it is best to avoid running exercises when sciatic nerve pain is caused by degeneration of the intervertebral disc.
Will a bone fracture cause swelling?
A bone fissure is actually a type of fracture. It refers to the occurrence of a fissure fracture in the cortex of the bone, but the stability of the bone remains intact. A bone fissure can also present symptoms such as localized pain, swelling, and restricted movement. Following a bone fissure, there will be localized bleeding, and the surrounding soft tissues may also be damaged, contributing to swelling. Therefore, in the early stages of a bone fissure, it is advisable to immobilize and rest the affected area. Cold compresses can be applied to reduce local blood flow, thereby easing bleeding and alleviating swelling.
Is running good for lumbar disc herniation?
Lumbar disc herniation is due to the degeneration of the lumbar spine. It results in symptoms from the herniation pressing down on the nerve roots, or the spinal cord, through a rupture in the fibrous ring. The disc mainly serves to cushion and absorb shock in the lumbar region. During running, the load on the lumbar spine and the compression are significantly greater compared to normal walking. Running might exacerbate the condition of herniated discs. Therefore, it is not recommended to engage in running, jumping or similar activities if suffering from a disc herniation. Swimming can be a preferable form of exercise that lessens the load on the lumbar spine.
Does a rib fracture hurt?
Rib fractures are generally caused by trauma, resulting in localized pain and restricted respiratory movements. In severe cases, there may be blood or fluid accumulation inside the chest cavity, or even respiratory distress, presenting symptoms similar to flail chest. Therefore, when a rib fracture occurs, the pain is very severe because the ribs are an important part of the thoracic cage, which is a crucial structure during respiratory movements. Thus, during breathing, the pain from a rib fracture can be quite intense.
Symptoms of lumbar muscle strain
Lumbar muscle strain refers to the condition where the muscles in the lower back are damaged due to chronic labor or sports activities, leading to excessive contraction of muscle fibers. This results in localized pain and limited mobility. The main symptoms include feeling soreness and pain during flexion and extension of the waist, and even feelings of weakness. The affected individual may not be able to carry heavy loads for long periods and, in severe cases, may not be able to stand upright and may require bed rest, accompanied by spasms in the lower back.
Lumbar disc herniation symptom diagram
The herniation of the lumbar disc occurs due to degeneration of the disc, causing the nucleus pulposus to protrude backwards from the ruptured annulus fibrosus, compressing the spinal cord and nerve roots, thus leading to a series of symptoms. There will be pain in the lumbar region, and restricted flexion and extension movements of the waist. Symptoms may include numbness in the lateral calf and dorsum of the foot, weakness in walking, decreased muscle strength in the dorsiflexion of the big toe and ankle. In severe cases, there may be loss of control over urination and defecation. Therefore, when a disc herniation occurs, it is important to diagnose and treat it early to avoid worsening of symptoms.
Osteoporosis nursing measures
Osteoporosis is commonly seen in postmenopausal women, elderly patients with degenerative diseases, and patients with disuse osteoporosis caused by long-term immobilization due to fractures, with the first two groups having the highest incidence rates. When osteoporosis occurs, it is essential first to provide psychological guidance to the patients, encouraging them not to be afraid and to face their condition correctly. This disease can be prevented and its progression delayed. Similarly, guiding patients to engage in appropriate exercises, such as walking slowly and practicing Tai Chi, can help increase bone strength. It is also necessary to advise patients to appropriately supplement with calcium and vitamin D, as osteoporosis primarily involves the loss of inorganic bone salts, particularly calcium and phosphate ions. Adequate supplementation of calcium and vitamin D can prevent some cases of osteoporosis. If osteoporosis is severe, it may be necessary to provide medications that promote bone formation and inhibit bone resorption for symptomatic treatment. Additionally, the diet should include foods rich in calcium to enhance the care of patients with osteoporosis from these various aspects.
What is the fastest way to treat sciatica?
When pain occurs in the sciatic nerve, the first thing we need to consider is whether it is caused by degeneration of the intervertebral disc. Accompanied by the rupture of the fibrous ring, it protrudes and compresses the nerve root, causing pain and numbness in the lower limbs, and even limited mobility. Once sciatic nerve pain occurs, it is essential to identify the cause so that treatment can begin as soon as possible. If it is due to degeneration of the intervertebral disc, early stages can involve back exercises and appropriate medication to alleviate these symptoms. For example, sleeping on a firm bed, wearing a lumbar support during activities, minimizing sitting time, or avoiding bending over to pick things up. Additionally, you can perform exercises like the "bird flying" and the "plank bridge" for back muscle training to help reduce pain symptoms. If these do not alleviate the pain, pain relief or anti-inflammatory medications may be prescribed for symptomatic treatment.
Bone fracture, hot compress or cold compress?
A fracture refers to the disruption of the integrity and continuity of the bone, leading to symptoms such as localized pain, swelling, and restricted movement. In the early stages of the injury, there may be bleeding, swelling, and pain. It is recommended to apply cold compresses to alleviate these symptoms. After the acute phase, choosing the appropriate treatment method, such as external fixation or internal fixation, is advisable. Once the condition has stabilized, applying heat may be beneficial to promote blood circulation around the tissues and aid in the recovery from the injury. Therefore, in the early stages of a fracture, it is important to primarily use cold compresses.
