I'm about to turn 22, and my problems started right after I turned 21. Started with some spells of fatigue and nausea, then in April I came down with some kind of viral infection... might have been coxsackie because I had a lot of chest/rib inflammation but I never figured out what it was. Recovered and felt pretty good for two weeks, then in the middle of May I started getting the dizzy/fatigued/nauseous spells telling me I was getting sick again, and then I got what I thought was a stomach virus but it never fully went away. For a while I was waking up every morning and vomiting like a pregnant woman, and I could barely eat anything. But I did have good days where I felt pretty good. The symptoms were really off and on. I was also constantly lightheaded/dizzy, and had some weird symptoms like hair loss and slight weakness in the left side of my body. I also had a lot of gas and bloating and would belch all the time. I had heart palpitations and anxiety, and headaches a few times a month. Finally, I started noticing that I had to eat at least every two hours or I would get really lightheaded, and because I was nauseous a lot I had to force myself to eat.
So that's how I felt from May to September with gradual improvement. In October, November, and December I felt better but hit a plateau. The main symptoms that lingered were the off and on lightheadedness, needing to eat frequently, on and off nausea, and gas pains. Then in January I started getting slightly worse... more stomach issues than I'd had in the last couple months, more lightheaded feelings, couldn't go as long without eating, etc. February has been horrible. Fatigue, nausea, feeling like my blood sugar is crashing even though it's normal, headaches, lightheaded, and more.
I have been tested for HIV, hepatitis C, had a CBC with differential, complete chemical profile, lyme disease test, gluten intolerance test, thyroid (was borderline hyperthyroid but had no antibodies), ANA antibodies, and more. Does anyone have any other ideas?
