I'm not  sure what to make out of this. I was bitten by bedbugs and I could see at least 25 incisions where they had cut and taking blood from me.  About five days later, I started experiencing pain in my back and went area underneath left shoulder blade. The pain got worse and then five days after the initial pain, it escalated So that  I had to go to the ER in fear that I was having a heart attack. Upon examination the ER doctor determined I had an impinged nerve.   I took the prescribed prednisone and Katara lack, and I'm following up with my primary care physician. But what is curious is that I could not tilt my head back. I noticed after 4 days of prednisone and Ketorolac, I can tilt back more today than day 3.   So the ER doc  was not aware of any vectors transmitted to humans from bedbugs that could cause the issue.  But this is so strange, I'd like to know if anyone else has experienced what I am experiencing. ps. I had a low grade fever at ER, but a fever of 99.6 on day 3 of treatment and 11 days after the bed bugs encounter.
