I am a 20 y/o female. I have been experiencing joint pain, stiffness, my shoulders, hips, and other extremeties they will pop all the time. My left shoulder is the worst it will pop and click back and fourth. My other one and my hip is starting to do it to. My mom has been diagnoised with fibromyalgia and severe back problems, but I dont think I have that. My muscles ache and after doing activites they get really sore. And when I try to hold something up like a brush or putting in a light bulb it will hurt and feel weak depending on the day, the weather, temperature. Also when I sit my legs go numb sometimes if I have it proped up on the other leg, my arm will go numb if I am laying on it for minute. And my feet get really cold too. And another thing after a orgasim I get really stiff and can hardly move. Im just wondering if this is normal for my age? Thanks brandy :)
