In brief: Allergic reaction?

An itchy rash on chest, arms and neck could be due to an allergic reaction.
If it suddenly occurred overnight, it is is possible that is is due to a reaction from something in the bed like bed bugs. Try OTC antihistamines (zyrtec, allegra) to see if rash resolves. If not, please see primary care provider.
