I'm eighteen years old and I've been experiencing joint pain lately, and was wondering where it's coming from. It started when I sprained my ankle last month, and then my knee started swelling up out of nowhere. Then my whole leg started swelling... The pain started from my ankle and knee to my feet, then my hips, and then my other leg. I then started noticing it in my fingers and wrists as well. The swelling is gone now, but I can't move each joint to its full range of motion, and leaning on any joint causes pain as well. Sometimes I get joint pain when I wake up, or when I've been sitting or standing for awhile, and especially after I do any kind of exercise. Please help!
