I am on my second Whole30 (last one was Aug 2019). Both times about 4-5 days in I’ve gotten terrible tinnitus (ear ringing). I don’t think that is a coincidence. My assumption is it is detoxing, or something I’ve added or removed from my diet.
It went decreased after finishing my first whole30, once I reintroduced all the food groups.
I’ve seen an ENT and determined that is not any of the obvious things: damage, structural, sinus issues, etc. His best guesses are natural aging (I’m 37), jaw clenching or diet.
My plan is to keep tract of it as I very slowly reintroduce foods
