For about 10 years i'll come down with flu-like symptoms fever fatigue dizziness that will only last about 1 to 2 days. It always feels like my Eustachian tubes. I have been a professional scuba diver and believes it all stems from my ears but im not sure. Most doctors just tell me It's allergies but I believe it to be something differently. This wears on me mentally and would like an answer.
