A few weeks ago, I got an egg-like knot on my knee, I thought I bumped into something, but then within two days, on both my legs and ankles, about 10 more little knots popped up, so now my knees are swollen. My left ankle is sw swollen that I cant tie my shoe and almost feels sprained. All my joints are incredbily sore, all the way down to my knuckles. The knots are red and warm to the touch. My obgyn says it could be water resistance caused by the depo shot but the knots are hard, and if I have beens sitting for any length of time, I need help up and its like me legs arent wanting to function right. Im a 23 year old, otherwise healthy person, so this seems weird to be happening, anyone have any advise on what could be causing this??
