Early symptoms of appendicitis
What are the initial symptoms of appendicitis? It is characterized by abdominal pain. The main symptom is abdominal pain that appears around the upper abdomen or navel, and some patients may also experience nausea and vomiting. Generally, two to three hours later, the abdominal pain gradually shifts to the lower right abdomen, which we clinically refer to as migratory right lower abdominal pain. This symptom accounts for about 80% of clinical cases, while some patients present directly with pain in the lower right abdomen, without transitional abdominal pain. Therefore, the primary symptom of appendicitis is abdominal pain, as described in these two scenarios. However, physical examination is also very important, typically revealing localized fixed tenderness in the lower right abdomen as the main clinical manifestation.
Difference between umbilical hernia and abdominal linea alba hernia
Umbilical hernias occur when the hernia sac protrudes through the navel ring, commonly developing around the navel area. Linea alba hernias occur between the xiphoid process and the navel, in the area referred to as the linea alba. The hernia that protrudes in this specific region is called a linea alba hernia. Anatomically, these two types of hernias are distinct, so they can be identified based on their anatomical location. Additionally, color ultrasonography can be used to detect the position of the hernia sac. If it is located in the upper abdomen, above the navel, it is generally identified as a linea alba hernia. If it is situated above or below the navel, it may be considered an umbilical hernia. Ultrasound can help differentiate between an umbilical hernia and a linea alba hernia.
Is lipoma serious?
Lipoma is a common disease in clinical practice, and it is generally not very serious, so there is no need for excessive worry. A lipoma is a tumor-like mass of normal tissue, commonly found on the trunk and limbs of the body. It has a clear boundary and is lobulated, soft, and may feel like a false cyst, painless, and grows slowly. Some can be quite large. Deep lipomas that might turn malignant should be removed promptly. Generally speaking, lipomas only require surgical treatment if there is suspicion of malignancy, if the tumor is large enough to affect daily life or aesthetics, or if malignancy is suspected.
Do lipomas hurt?
Lipoma is a common clinical disease characterized by tumor-like normal adipose tissue, often occurring in the limbs and trunk. It has clearly defined margins, is lobulated, soft in texture, and may feel like a pseudocyst, with no pain symptoms. The growth is slow, and some can grow quite large. Deep-seated lipomas can potentially become malignant and should be surgically removed promptly. Another type is the painful lipoma, which often occurs in patients with a family history. These tumors are usually smaller and commonly distributed symmetrically. However, most lipoma patients do not experience pain symptoms; it is only the painful lipomas that are painful. These are also characterized by a family history, symmetrical distribution, and smaller size.
