Im a women , about 1 year when i stand more than 15-20 min my hip joints are pain, its more pain when i seat, but if i lay down for few hours then it will better , sleep one day the pain will go away..?

Any history of injury or overuse of your hips? Other than these 2 factors, arthritis or bursitis of the hips are possible causes of pain after standing. Studies such as X-Rays,MRIs or CT scans could shed light on the diagnosis. I recommend consulting a rheumatologist or orthopedic specialist to evaluate and advise you. The type of testing is dependent upon the findings during your initial exam
