I know this is long - bear with me, it's so important. OK- I'm 15 years old and I've been sick for almost 3 years now. It started out with headaches, and over time, more and more symptoms have popped up. Here's a list of them, in order that they began. -chronic headache -chronic fatigue/tiredness/weakness. (always falling asleep, exercise is over-tiring and difficult) -sensitivity (muscles hurt when they are touched, even not that hard, and that spot will feel bruised for a while) -night sweats and chronic low-grade fever -swollen lymphnode on my neck.. behind my left ear. it's been there, getting bigger and smaller randomly, but hasen't gone away, for 2 years. doesn't hurt or anything. -joint stiffness and pain -joints grind together and pop when moved (and it hurts) -dizziness/lightheadedness (especially when singing and exercising) -random spontaneous heart pain (usually lasts anywhere from 10 seconds to a few minutes, I could be perfectly relaxed and it'll start, but not too often) -short term memory problems -increased thirst (this one is recent - I'm always thirsty, when before I never really was) -ever since I've been more thirsty, I've been getting random bouts of feeling sick to my stomach. Feels like I'm gonna throw up randomly for 5 minutes to a couple hours -seems like my immune system has also been bad lately - 4 colds this cold/flu season, when it's usually 0 to 1 - and I wash my hands plenty I've seen 3 different primary health physicians, a neurologist, a jaw doctor, a headache specialist, a naturopath, and probably others that I've forgotten. I got my head MRI'd... no tumors! And my blood taken several times. The neurologist prescribed a muscle relaxant because he thought it was muscle tension causing it. It did nothing for me. The jaw doctor said I have TMJ but we haven't gone back to him. The naturopath put me on a very restrictive diet for a month - no gluten, dairy, red meat, and a bunch of other seemingly random things (like red dye #40 and mustard). That did nothing. I completed a course of biofeedback at the Children's Hospital because they, too, thought it was muscle tension, but I passed with flying colors, and did exeptionally well from the start, and it didn't help - plenty of evidence that it's not muscle stress or tension. I went to see a new doctor recently and he took blood and urine samples. The only thing he saw weird was my iron, which was at "28", but at the time I had a bad cold so he said that can increase your iron, so my iron is too low. For several weeks now I've been taking the iron he's prescribed. We're going again next week because all that has happened is that my dizziness and stomachaches have increased in frequency (the dizziness probably because I'm in a play with a lot of singing). And I'm not feeling any better from the iron pills. What's wrong with me? I just want to feel better. P.S.- Also in the past year I've gotten breast cysts 2 seperate times...both times they got infected. I don't know if it's at all related but might aswell put that out there.
