I've had several anaphylactic episodes (flushing, pressure in head, rapid heart rate, near syncope) in the last year and I've had persistent symptoms ever since the third attack in February of this year. These symptoms usually manifest as achiness/pressure around my sinus areas and dizziness and I occasionally experience pain in the back of my head/upper neck as well. I also experience numbness/tingling of the affected areas of my face from time to time.
These symptoms are often, but not always, accompanied by hypertension (which I've never had before), sometimes as high as 160/90. In the last 6 months I've seen 9 doctors and had blood work, urinalysis, MRI, CT scans, and a tilt table test all of which yielded normal results. Just bending to lace up my shoes often throws me into a headache with some flushing and dizziness-bending and crouching often bring on these symptoms or worsen them, though not always.
I can pinpoint the day these symptoms began-I had an anaphylactic attack which lasted about 30 minutes (and I also had a sinus infection at the time), so I'm assuming this event somehow triggered my problem. As a rule, my ears always feel full sometimes to the point of aching when these symptoms come on, but sinus infection and allergies have been ruled out. Any idea where I should go from here? So far I've seen an endocrinologist, ENT, neurologist, allergist, and several general practitioners but I still don't even know if the root of my problem is neurological, cardiovascular, etc?
