Dan,
They did tell me that I could experience the lump feeling in throat, it is one of the "positive side effects" so they say. But when I was choking, the feeling that ran across my back and into my other arm was almost like a transfer from one side to the other (without losing the pain in the original hand) if that makes any sense.

The nurse just called to check on me, I explained my experience, her response was" HMM, maybe the medicine didn't go completely to the same spot. The lump feeling is normal, but when anxiety spikes it could cause the choking feeling." I said what about the pain across my back and now worse in my left arm? She really couldn't answer that...I know....don't go back to her....I see my hand surgeon next week and we are gonna have a serious talk!

So anyways Dan, sorry to babble on about mine...is the injection site very sore & tender where you had you block done? Make sure you aren't running a fever, not having bad swelling in the area and if the pain feels "abnormal" call the Dr. and get it checked out, nothing to mess with. My injection site (front of neck) has a tiny bruise, but very tender. Let's hope for relief and a better way to get it!!
