In recovery from anorexia. i started to have bad pain in my hips when i began running and it's been continuing all the rest of the day. walking hurts?

Hip pain: I suspect that you developed bilateral tendinitis or bursitis of your hips after starting to run after a prolonged absence from exercise. I recommend that you rest your legs and, if you can tolerate them, take anti-inflammatory medication like ibuprofen or naproxen for a week or so. If no improvement, see your physician for evaluation.
