Dear Trickmaster. Sorry to hear of you condition backsliding. And after getting better too. I think the more severe the AF condition the more complicated the body gets. But, I can relate to the neurological conditions. Mine have gottenworse the past year. And I did feel 20-30% better last year too, but still a far cry from any normalcy.
My brain symptoms are the second most deliberating, as anxiety being the worst.
Mine are lightheadedness, impairment of vision, coordination, balance spaciness and sometimes like my head it detached from my body. These symptoms vary in degree each day. Sometimes not so bad, but other times, when I'm our driving... I have to stay very focused and this concerns me. I too wonder about the cortisone levels, as you mentioned cortison acts as an anti-inflamatory and I wonder if the brain can get inflamation. I noticed when having a head cold the past week, I did take mega dose of Ibephrophen 2 times and my head did feel better. And when I had dermatitus last month, the dr. had me use topical steriod cream which cleared that up, but too I felt 20-30% better because of the absorption of the steroid cream. I documented all of this.
I sure hope this naturopath can help you Trickmaster.
Keep us informed as to what happens.
