Last Wednesday, my fiancee began noticing flesh-colored bumps on his upper arms and part of his back...?

There were very few bumps, so we disregarded them. The next few days, he began to get more and they started itching. He went to the Dr. on Saturday and he didn't know what it was but he gave him some medicine for the itching. The medicine just made him high and not think of the itching. He's went the past two days and they still don't know what it is. It's spreading more and he has bumps on his arms, chest, back, and they're halfway down his legs. None on his face, hands, or feet.. He doesn't have a temperature or anything... It's just a lot of itchy bumps. Any idea what it could be or how to fix it??

I left some out...We thought maybe it was our fabric softner, so we stopped using it all together and it didn't change. Everything else has been the same. We tried Benadryl and it didn't clear it up or anything.

Sounds like a reaction of some sort or even heat rash. Give him some Benadryl (it may solve everything, but will definitely help with the itching) and if it doesn't go away or gets worse (any new symptoms), get a second opinion.
