If you can feel a strip in the left lower abdomen near the hip bone, it may be caused by physiological factors or pathological factors. If it is caused by pathological factors, you should promptly go to the hospital for ultrasound, CT and other related examinations to clarify the cause and then treat the symptoms. A. Physiological factors: 1. Iliotibial bundle: the bar felt in the left lower abdomen near the hip bone may be the iliotibial bundle. The iliotibial bundle is the thickest fascia in the body, starting at the iliac crest and ending at the lateral tibial condyle, a tendon that combines the gluteus maximus and the broad fascial tensor, which can be touched on the left lower abdomen near the hip bone. Iliotibial bundle is one of the normal structural tissues of the human body, no special treatment is needed; 2, other physiological factors: such as persistent stool, when there is persistent stool, may be in the left lower abdomen near the crotch bone to touch the strip, can promote defecation by appropriate more dietary fiber-rich food, such as celery, spinach, etc., can also follow medical advice to take laxative drugs, such as phenolphthalein tablets, lactulose, etc. Second, the pathological factors: 1, intestinal diseases: when intestinal diseases appear, can be felt in the left lower abdomen near the hip bone strips, such as intestinal obstruction, intestinal tuberculosis, sigmoid colon tumors, etc., can be manifested as different degrees of abdominal pain, vomiting, abdominal distension, anal stop exhausting defecation, accompanied by fever, weakness, wasting, anemia and other symptoms. Treatment should pay attention to dietary hygiene, avoid eating irritating food, avoid getting cold, avoid smoking and alcohol, and actively treat the original disease.

For intestinal tuberculosis, oral anti-tuberculosis drugs, such as isoniazid, rifampin, streptomycin, etc., can be taken under the guidance of doctors. If necessary, surgery can be performed to remove the diseased intestinal segment or repair the intestinal segment. If the condition of sigmoid colon tumor allows, the treatment of surgical removal of tumor should be carried out as early as possible, and according to their specific conditions, radiotherapy and chemotherapy should be applied for adjuvant treatment; 2.

For urinary stones can be treated by applying drugs for lithotripsy, such as tamsulosin, under the guidance of doctors, or by extracorporeal shock wave lithotripsy, surgical stone extraction, etc. If it is caused by urological tumor, the treatment of surgical removal of tumor should be taken, if necessary, auxiliary application of radiotherapy, chemotherapy, immunotherapy and other treatment methods; 3, gynecological diseases: gynecological diseases can also appear in the left lower abdomen near the hip bone to feel the bar, such as cysts, tumors, etc., can be examined and diagnosed through abdominal ultrasound, CT, etc. Ovarian cysts can be treated by ovarian cyst debridement; gynecological tumors should be treated by surgical removal of the tumor, as well as the application of adjuvant treatments such as radiotherapy and chemotherapy; 4.
