Lump on arm

[ZepDoorsFloyd41]

Hey guys, so swim just got his 10mg immediate release Morphine tabs. And he banged them. Right as he was injecting, this big lump formed on his arm, about the size of a quarter in diameter. It doesnt hurt though. He might have missed the vein. But he thinks its because he decided to use a tourniquet for the first time, and, like the idiot he was, he forgot to loosen it/untie it before his shot.

Ok then he shot a second time, in the other arm. He didnt use a tourniquet this time, and he knows he hit the vein. Everything was good. But then liek a couple minutes later, this smaller lump gradually appeared. Unlike the other lump, this lump is much smaller, and took some time to appear.

Now he's thinking its the morphine doing this, there must be some fillers or gel inside it. He doesnt know. Any input on this is greatly appreciated. Thanks
