I reallywish I could help u with advice, but I too am in the same situation and have no answers. I was about to ask if uve had ur thyroid checked and then I saw that u said u have Hashimotos. I also have that and know that headaches and dizziness are among many symptoms. Are u doing well and on the right thyroid med dosage? I am on cytomel after being switched from synthroid, and although my TSH levels are where they're suppose to be and a lot if my symptoms have let up, I still feel like ****. Still have body and muscle aches, fatigue, and my excruciating headaches everyday. I too have been to a neurologist who then sent me to physical therapy twice a week for headaches and horrible lower back pain. I've had MRIs that have come up with nothing. The physical therapist seems to think my daily headaches come from my posture and my large breasts putting strain on my neck. My headaches are so bad. I have been put on topamax which completely took my headaches away, but I had to discontinue that due to the overwhelming side effects of dizziness and brain fog. I have recently started experiencing blurry vision and it's worrying me. I don't know if it's from my headaches or my Hashi. My bad body aches are returning too so I'm thinking I need to have my TSH levels checked again. I'm sorry I canthelp, but please keep me updated on what u find out. Best of luck.
That was suppose to say I feel like crud. LOL
