I have CRPS in my right shoulder and have had 3 nerve block injections. It hurt a bit for about 1/2 hour or so but not much. The pain is really from the muscles and not the nerve pain any longer. I was in so much pain before the nerve block injections you could not even touch me, clothes hurt, covers hurt, everything hurt. My skin was on fire. Now the neuropathic pain is almost gone.
I see the pain management doc in the morning to find out if I need any more nerve block injections or just continue with PT to work on the frozen shoulder that has been a result of the CRPS. NOW that is painful!!! I've got some residual shooting pains down my arm/deltoid and tricep muscles that jolt me but the frozen shoulder is causing the majority of my pain at the moment.
Wishing you much luck that the nerve block injections give you relief as they did me. Heat helps immensely, not ice! Ibuprofen. I switched from percocet to Ultram this week and it seems to be helping, not making me as drowsy during the day!
I am also taking Neurontin at night.
I also have MS so it complicates matters just a tad bit...like CRPS isn't enough!
Take care and Welcome to NT!
