Last few weeks, I'm having this pain in my joint areas like - under the knee, the elbows, the joints in my fingers, the ankle. It is more like a discomfort. All I feel like doing is jerk my legs or twist my ankle, but that doesn't seem to help. It becomes so unbearable that at times, I can't sleep at night. The only way I can stop it is if I can successfully divert my attention to something else. I am not sure if it's exactly in the joints or the surrounding area with ligaments or the muscles around it. I used to have this problem since the time I was a kid, but it had stopped - last couple of years, I didn't have to suffer from this. Now, it has come back. I would like to know what causes this? And how can I stop this once and for all?
