Some of you may no that i'v not actually taken steroids before but occasionally do the injections for my friend ben.
Yesterday i injected 1ml sust 21g 1.5" needle. He immediately noticed the area was a bit swollen. He said it doesnt matter but im soft of worried cause the other shots i'v done for him didnt do that.
So i sorta feel obligated since i was the one that injected.
I shot the quad deep enought and i thought i went slow but maybe now slow enough.
Everything was sterile. I asked him today what it was like. he said its still there but theres no pain at all. Its not red or warm.
questions-
Did i inject too fast. it took about 45-60sec.
Could it get worse and get me in the shitter?
Should i tell him to take ibuprofen or something just incase?

No pain, not red, not warm, just the swelling!!
i'v read through lots of posts but they all mention pain.
