I am a 31 yo female with no health problems until fairly recently. For about a month now, I have been getting lightheaded, pressure headaches, and extreme fatigue. It comes and goes for no apparent reason. I went to the doctor and he ran a general blood test. My results were normal. He tested my TSH, T4 and T3. The T4 was slightly high, so they tested it again. It came back normal. He also did a CT scan and it was normal. I eat extremely well and workout 7-8 hours a week. I stay hydrated all day. I am not underweight nor am I overweight. The only prescription that I am on is birth control, which I have been on for a long time. When I feel the symptoms, I get withdrawn and am in a bad mood. I don't know what to do and it is starting to affect my work and recreational lifestyle. Within the last couple of days I have been feeling a deep ache in my arms too. I have been gluten-free for a year and half due to gluten intolerace and Celiac Disease in my family. Please help!
