I have suddenly begun having pain at the joints where my upper leg bones meet my pelvis. Both legs. if I hunch over a little bit it helps; if I stand straight it is worse. If I arch backward it gets worse yet. It is affecting my walking. It has been going on for about 2 weeks, at about the same level of pain and it occurs every time I stand or walk. It also hurts if I life my legs while supine in bed.
