HI i was taking fragmin injections until a few weeks ago due to a ruptured achilles tendon. It is a little painful to start with but after a injections you hardly feel anything as your technique improves! Did have a lot of bruising at the injection site though on the side of the stomach area. Just remind yourself of how lucky your are and that diabetics have to go through this type of thing for many years. Thats what i told myself anyway to make myself feel better lol.
