Thigh pain may be caused by muscle strain and hip joint strain, or it may be caused by femoral head necrosis or lumbar disc herniation. 1. Muscle strain: If you do exercise in an improper way, it may lead to muscle strain in the thigh area, which may lead to the symptom of pain in the thigh. 2. Hip strain: If you often exercise, or sit for a long time and stand for a long time and bear too much weight, it is easy to cause hip strain, which will lead to the phenomenon of pain in the hips. 3. Necrosis of the femoral head: Necrosis of the femoral head is usually related to long-term drinking or frequent use of hormone drugs, and the main symptom is localized pain. 4. Herniated lumbar disc: If the lumbar disc is herniated, due to the compression of the nerve root, it is also easy to have the symptom of pain in the hips. It is recommended to actively go to the regular hospital for relevant examinations, to clarify what causes, if the disease is caused by factors, to actively comply with the doctor’s instructions, so as not to delay the condition.
