Had a hearing test today, felt I was missing certain frequencies, was told I have calcification in one ear and was a bit young (58) to have it but not unheard of. Researching on Google found hypo came up as a reason. I suffered deafness before being diagnosed hypo, which was quite severe, but recovered. Figured it was happening again as need meds increasing next week and do have a small amount of hearing loss but nothing to worry about at this stage. Calcification another one to add to my list!
