Don't do the inside of your thighs, just the outsides, don't do where you actually SIT on your butt, since there is greater chance for infection,try not to do it where your clothes can rub the shot spot, don't scratch the lumps for at least two days, arnica helps with the itch and sting, and according to my doc, anywhere you can pinch an inch is fair game since it's a subcu shot.
That's all I remember except I didn't do my arms either, because the lumps and I were absolute best buddies and they hung around for weeks. I always did the shots where the lumps would be hidden. If you use the autoject, play with the depth, it really can make a difference for each person.
Good Luck and hugs to you!
