Hi there, yes the injection site "ouch" can be just crazy at times. I have been using the auto injector for the longest time, and with it I found that the injection site pain was not very nice....so i stopped using the darn thing, and do the shots manually. Yes I had to give in on some of my deoendency, and have my wife give me the shots behind my arms. But......no injection site pain at all, and not very much swelling....complete turn around.
But when I did or will likely get in the future, site pain, using an ice pack, or cold towel helps, and in some cases, going the other direction (using warmth) has helped others as well. Massaging the area helps as well. Another thing that shared solutions told me, and it worked as well, was to work in some lotion into the area, seemed to help with the redness.
Another thng that helps me too, is to use a lotion or something that has a numbing effect - like something (I for the life of me remember the name of it) but u use it for bee stings and things as such.....
Thats what I have tried, and works to some degree - but ever since i discarded the injector, i have been trouble free.
Have a nice day
