This has been going on for months, I have strong pain in my arms and legs. The pain lasts seconds, but happens up to 15 times a day, although some days it doesn't happen at all. I am fairly healthy, and I am 22 years old. I told my doctor and she said I was to young for it to be anything serious and I shouldn't worry about it. I'm worried! It seems to be getting worse and it happens more often. Anyone have any ideas?
