I have a rash on my back.It starts in the middle of my back,actually there is two patchy areas over my lung area and the rash has spread up my back to my shoulder area.It has also been accompanied by a cold,runny nose and stuffed up,cough, head ache,sore throat and that's about it as far as any symptoms.The rash is a little itchy but not bad.I have had it for 3 days now and no one else in the house has it.The rash looks like little red bumps,I did take some allergy medicine and I thought it was helping but it has not.
