For 4 months now I have had severe pain, burning & cutting sensation from c 6&7 & t 1,2,&3 which radiates over to r scapula & under r arm. Causes burning pain over entire scapula. I think what brought this on was I had a severe sneezing episode while sleeping & I got up on r shoulder & felt the most intense burning, tearing pain over r scapula. Any suggestions of whAt might b wrong will b appreciated.
