Yeah, I had similar experiences to Skullchick's and Jenny's. I wore different hearing aids for almost 20 years.
1. No matter how many molds were fitted and refitted, they eventually hurt after several hours and had to come out. Strangely, the behind-the-ear aids were less painfull. Maybe it was they came later with better inserts, or maybe I just got used to them.
2. Yes, sometimes I couldn't wait to get alone so I could take the damned things out to cut background noises and massage my ears, ha ha ha.
3. It's been said lots of times here at AD, but when some hearies see I had devices, they expected perfect hearing. If not, it must be my fault for not paying attention or "not trying hard enough."
4. They no longer do me any good. I miss not hearing some sounds, but I don't miss those infernal pains in the . . . ears.
