I'm 61, Female, 200 Lbs, Work Midnight Shift; I'm Staying

I'm 61, female, 200 lbs, work midnight shift; I'm staying exhausted, not just tired, but yet can't sleep. When I do sleep, it is sound sleep. I stay thirsty, can't get enough of anything to drink, but I don't drink any alcohol, eating just to be eating is the best way to describe it. joint pain all over, mainly right hip, swelling of right leg down to and including the foot, with sometimes pins and needles tingling in same leg.
