This happened to me once before. I ran out of 1.5" pins, so instead of getting some more(laziness), I used a 1" I had left from site injections. This was a bad idea! The AS must not have went intramuscular, because I was leaking and I had a painful ass knot on my cheek for 8-10 days. the swelling and pain got less and less each day.
This could be a possibility, even though you did use a 1.5"
Just a little info from personal experience.
I hope everything turns out OK for your buddy.
Good Luck
