This sounds like my ear history all over. Chronic ear infections & Antibiotics as a child, tubes in ears, the whole thing.
Last year, I had a blood test that showed I was severely low in B12- and I eat meat. I am not able to absorb B12 or folic acid from my food.
I started B12 shots and folic acid supplements 11 months ago- and I have not had a single problem with my ears since. No infections, no drainage, no pressure, no pain- my hearing has even improved.
Please consider a blood test to check B12 and Folic Acid levels.
