Hi!I am having sharp pains (spasms) on my right forearm and have some rash spots that appearred in the last 24 hours along my arm.  I have had radiation for breast cancer which ended on Sept. 20, 2011 and I also have herniated discs in my neck.  This pain is so severe and consistent that I cant sleep.  Any idea what the cause could be?   Im getting very worried.  Thank you
