I used a clamp for a few years. Never had any problems like you Describe. In fact, I have one on now and I don’t even feel it and I forgot I had it on so I’m glad you reminded me, so I can take it off.

The Weisner clamp has t different sizes in the package. They sell it at Amazon. Not sure if it will work better than what you have now, but you seem to have problems with that.
