I am 39, for the last year I have had joint pain in my hands/wrists, knees, hips ,ankles, sometimes back . hand and knee pain are constant and are the same on either side of my body, but vary at times (worse before periods, with bad weather, cold weather, after exercise). I have seen my PCP and a rheumatologist who did blood work -all normal, RH neg, neg C reactive, normal sed rate/cbc,thyroid.
