Hi, I'm so sorry that you've had this complication - VERY scary!!
You need to talk with forum member "Horizontal Helen" - she's had breathing problems as well.
I am curious to know where your surgery was preformed and by whom. You could PM me that if you aren't comfortable posting it.
My Long Thoracic? (what I suspect anyway as the problem?) occasionally becomes irritated (by wearing a bra for too long or overdoing any physical activity) and I have breathing problems. Sometimes scary enough that I run to the local fire station for help. Are you able to apply ice to painful or irritated areas?
I will say that over the past 5 years my burning and other nerve pain has lessened... but it always comes back - either because I did something I shouldn't have, or due to weather changes.
Good luck to you, I hope that these serious effects will subside when your nerves have calmed down or regenerated.
Anne
