Thanks. I'll contact the nurse to have her explain again why she advises against it-- I don't recall it being about leakage. The reason it came up in the first place is that I told her I had learned on this site to pinch-- and I was sort of proud that I had learned that without her. Extra: I know at the beginning I was horrified at the thought of injecting into my belly, so I tried my thigh. That was a disaster.
