I found that the belly was best becasue it had more 'fat'. I agreee to make sure the sport is 3 inches away from navel. I foudn the techniques the nurse used made a big difference. Make sure she takes a pinch of 'fat' and goes into the fat ( not directly into stomach). My nurse went in at a slight angle.
Have the syringe at room temp. I was best with a fast smooth injection ( and not a slow drawn out injection)
Afterwards use an arnica antinflammatory cream ( I use inflamyar by Pekana from Germany)
This made all the difference.
However the medication did not work for me.. I am one of the non responders unfortunately.
