In my family case, belt is out. And in general, if we have a serious ill, not a cold I mean, my parents try to do our live the most confortable they can.
Visit to doctor
In my family the belt is removed and my mother or father is with me all the time at the doctor. The belt (and I think now the tightbands, too) go back in place after I have seen the doctor at the next possible place. Mostly the next disabled toilet or something similar where I can be supervised by putting both back in place. If we are there by car I'm mostly allowed to to it at home.
I asked to remove the belt the day before, went to the doctor, and put it back on after
No change since my answer on Misterpoll...For gynecologist and classical doctor too.
The belt is unlocked.
That gel probably contains Lidocain or a very similar local anaesthetic. Similar to when you get an injection at the dentist for the treatment or if you ever has a wound that needed stitching, the stuff that is injected so that you feel no pain anymore, Medically speaking, it is a sodium channel blocker.
