Painful Cysts/Balls in my upper arm?!

Painful Cysts/Balls in my upper arm?

Hi. I just recently got a Haldol shot on June 4th. Haldol is used to treat Schizophrenia and is a medication used in a monthly shot. Anyway, I was told some people develop lumps in their arm. 2 weeks after the shot I noticed one ball in my arm. Suddenly there's 4 growing painful cysts around the same area of my right arm. It started off small, and now I feel 4 rubbery cysts aka balls. They're very painful and are causing me problems whenever something lightly brushes against my right arm. The pain now is near my shoulder but no cysts reported there yet anyway.

If it's Cancer, can anyone tell me what it'd be called? I don't have any symptoms like fatigue and nausea.

Is this normal for a Haldol shot?

Ask your doctor if it's cancer! I wouldn't know unless I looked at it and did tests on it! Go ask your doctor! Hurry! You don't wanna mess around about something like this. You should have seen your doctor as soon as the symptoms got weird... (4 cysts that hurt whenever they're touched).
