hi ,i work in a hospital and they use a numbing cream called emela ! i am in uk so it may differ ww but it is very thin and flexible like a catheter , they put lube on the rod so it slides inside too !
say about the pain level??? do they do this for catheters too???
not painful to insert a catheter at all we just use lube for that !
for the camera either??? wow if so!
maybe a little for a camera as they have move it about more but not pain as such just little uncomfortable!
