I'm a girl aged 16 and these pains have been going on since i was 12. I am not in year 11 and they started in year 8. At one point I couldn't move and I was in a lot of pain especially last year but this year its got worse. I've had swabs, scans and blood tests and they still cant find anything. I don't know how many times I've been to doctors and the hospital about them. They're not as bad now but when I've had abit of alcohol in my system these pains get really bad, and sometimes I cant walk but I really dont know what it is? and I starting to get worried, can someone please help me out?
