I am pretty much same situation as yours, my tonsils were removed when i was 6 years old and i don't know if my adenoids were remove too.
In term of symptoms, i have bad/metallic taste and fecal breath same as yours.
I have ENT appt. tomorrow and would appreciate if you can clarify the followings
1. You said "my ENT found cysts where my tonsils were", i assume your doctor didn't knew the cyst before going to surgery, is that correct?
2. Which one do you believe was the root cause of your BB, cyst, adenoids removal or fixing deviated septum?
3. I don't have insurance and would appreciate if you could share total cost of your surgery?
