Hi, Thank you for your query. There are a lot of reasons that can cause leg pain. The problem may be musculoskeletal, neurological, vascular, metabolic, hormonal, idiopathic and so on. Even sedentary lifestyle with inappropriate leg positions can cause it. Do bicycling and stretching exercises. Through physical examinations and imaging are required for evaluation. Consult with a Rheumatologist. Hope, this helps.
