Hi. So I'm in a lot of pain all over my body. It started with my right foot. It seems to be spreading. Both my feet hurt to the point that I'm limping often in the morning for about 2 months now. Then my right elbow started hurting shortly after. I can't straighten it all the way and it hurts when I try to , pull,or push things sometimes. After that, the left side of my jaw started hurting, now it's both sides. It hurts to open my mouth wide. Then my neck and upper back started hurting and being stiff. It hurts when I turn my neck to either side. Then my left knee started hurting when I squat down. Now my left hip started hurting when I walk or move the joint. I'm 21 and female. I've been athletic all my life, but haven't exerted myself lately for fear of making it worse.What's going on?
