About 3 weeks ago I began having a constant hissing noise in both ears and last night I began having a bitter taste. I have not been around loud noises have not noticed any difference in my hearing. Many years ago I did rupture an eardrum and have experienced a minor Long-term hearing loss. I am 64 yrs old and do take many vitamins (special bariatric formula) and minerals (iron, zinc, magnesium, calcium citrate) as I am post gastric bypass of 11 yrs. I also have not had any cold, flu or allergies.
