It seems to be a common thread among us w/any sort of neuropathy. Kind of like the high arch/foot issue.. I don't know about you, but I've had both these problems to varying degrees LOOONG before I 'found" PN! I think It's just that the meds we take [& their s/e's] and all the other stuff in our lives attune us to this stuff much more than we'd like. I've found that my state of 'ear-ness' varies w/new medical issues and my IVIG treatments [lots more goes into me, than comes out?] Even tho my BP doesn't rise, inside I feel like it has, ergo my ears roar more.
I will leave it to Mrs D and Rose to address the calcium types [I feel a dummy and ALWAYS have to look it up all the time!] and the potassiums, magnesiums and anti-inflammatories...
I hope dearly you sort out what YOU need for YOU! I'm still tinkering w/mine?
Super good thoughts! - j
