My skin was getting bruised, red, swollen with knots. I figured that my skin was beginning to break down.
Doctor gave me a perscription cream to try: MOMETASONE FUROATE CREAM 0.1%

Here is what makes it effective for me: Alcohol cleanse (LET DRY!!) Give shot then put a dab of cream on and rub rub rub rub for a minute or two.
Then put a dab of cream on a small bandage and place over shot mark.....leave on over night.

Ahhhhh.....less redness, no hard lumps, skin feels much much better......lets hope it lasts.
The key is covering the injection site and sealing it with a band aide. A large irritated area can even be covered with saran wrap and taped on over night.
