Stop using the heat on the site...that could be part of the problem! Try the ice. That's my experience! I know that there was a batch of dull needle complaints here a bit ago from Shared Solutions...so you might want to call them and ask for some replacement meds!

As far as rotation, whatever works for you. Up a little, down a little. It just has to be subcutaneous...not muscle...pinch an inch!

I never used my arms, only because I work as a landscaper designer and am out in the sun a lot and the sun made the welts stay...so I only used my thighs, buttocks, stomach and the backs of my legs. I am sort of a thin person, so finding areas was not easy. I found tho that lots of room in the buttocks and backs of my thighs. Stomach was a great area around my belly button. My GPs nurse showed me that. The ice really helped, just putting the needle in at a 45 degree angle was the trick! No problemo!

Keep asking questions Natalie.

Hahahahaha RW...Strange people is right...you fit so well!!!
