I have been doing self-injections for 4 months now. The needle is long and it goes in deep. I surprised myself by not having any problem doing it. I never thought to ask my doctor and I may next visit, but I was wondering if there is a problem exercising (power walking) right after".
No, but I do mine (yes I still do HRT) at night. Doctor said that was a good time because that is when the body rest and rebuilds it self.
I went swimming shortly after i.m injection.
