I'm 25 years old and I've been extremely healthy until a few months ago. I woke up one morning and noticed my spine was extremely painful to touch, top to bottom. Upon looking further, I noticed it was swollen on one of the lower vertebrae. This stuck around for a few days but came back 3 more times in 2-3 week increments. Between episodes I noticed I was very fatigued, achey(especially in my spine and elbows), dizzy, and nautious. I had fairly severe diarrhea and at one point was going 6-8 times a day. I also had 2 lymph nodes in my neck as well as my thyroid swell up. Its been about a month since I've had an episode but I still am achey in my joints, extremely fatigued and have one lymph node in my neck that remains swollen, although not at all painful. X-rays have come back normal, blood tests have ruled out viral infection and auto-immune diseases. It was found that my WBC count was slightly low and my ferritin levels were extremely low (6), which would explain the fatigue. I've never had a problem with anemia, I have a healthy diet and even after taking iron supplements, my levels are still very low. Nothing seems to fit and doctors can't diagnose me and seem to have given up. I just want to feel good again! Help!
