Well to condense a huge history over 10 years- Dx with EDS by both the “big” docs in the field. Positive MCAS by the Boston big wigs and positive hyper Pots at Mayo- years of headaches, crushing neck pain, fatigue, vision issues, pallor, heart rate issues, hearing problems including perilymphatic fistulas etc. Sure sounded like ICP problems to me. Took Dr D’s book to my doc who was all for it- tried diamox at multiple doses for 65mg- 500mg x2. Every time no matter how low the dose my headache would change and slightly improve but I would be flat on my back with vertigo and fainting routinely. So we tried all the things mentioned, making sure i was hydrated, even using IV therapy, always checking Co2 levels and optimizing. Supplements with Collar, Vita C. Magnesium etc. Still no luck. Fainted so many times I had to have facial reconstruction surgery. Tried multiple different doses of topamax and same issue. Countless MRI’s show empty sella and “tight, tissues etc which led those in the know to think high ICP. I even let them put a bolt in my head and monitor me for 72 hours but my pressures although showing some spikes were essentially normal. Then many felt i was having leaks and after seeing the best two leak people in the country that was ruled out. On and on this went and i finally conceded and had a chiari decompression although the tonsils were not low I was told the CSF was severely restricted. with that I also had a cervical instability surgery. Well it was ll ugly and complicated by multiple problems but the long and short i didnt get better i got worse. Much worse, disabled and unable to work. Headaches and neck pain 10 x worse along with all the other symptoms. Tried all the ICP treatments again no go-tried MAST cell meds to no avail. I dont know anymore. The crazy thing is i will have certain 2 or 3 days maybe every month when i will only have a slight headache and my vision is clear and I can think and get out and no dizziness etc. Its amazing and then i wake up the 2nd or 3rd morning and bam right back into the massive headache, neck pain fatigue etc. I have thrown my hands up at this point and so havent most of my doctors who are great and the ones mentioned on here but we are all frustrated at this point. So my friends any thoughts??
