My worst gluten attack took 8 months to resolve, but I eventually went to a naturopath who suggested 'live' prebiotic, not the regular bottled kind. These are kept in a fridge, and some pharmacists sell them. These settled my guts so quickly, and I returned to normal.
You seem to have the problem of symptoms overlapping, different problems with some of the same symptoms and unfortunately happening at the same time.
I hope you are continuing to follow-up on these heart / blood pressure issues and get a full understanding of "what is happening to me".
Best wishes to you, my friend!
