I Have Hard Bumps Where The Injections Of Byburean Were

I have hard bumps where the injections of Byburean were administered. They are NOT going away. I saw my doctor last week and his simply said it is a reaction from the injection. Not very helpful I have decided to stop this medication from the answers I received on this site. I really had decided BEFORE then.
Any suggestions? I tried a heating pad and also ice. Nothing helps. ??
