my shoulder feels sunburnt but its not...whats happening?

Ok, a couple weeks ago i had H1N1.  Shortly afterwards, my shoulder felt like it was sunburnt.  I looked at it and it wasnt red at all.  Sometimes a sharp pain will shoot through my shoulder and make all the skin around it feel as if its burning. Two days ago i slept on my neck wrong and it caused alot of pain in my shoulder.  Just today i looked at it and on my shoulder there is a cluster of red bumps.

Hi,
An allergic reaction to the H1N1 shot could have occurred immediately on taking the shot. The appearance of red bumps and nerve pain may be due to a viral infection. Another possibility is that there is a  nerve compression in the spine and the skin bumps could be a coincidence. Please go for an MRI of the spine and arm and consult a neurologist and physician for diagnosis and treatment. Hope this helps you. Take care and regards!
