Ongoing rash

[Stonebridge]

I completed 5 1/2 weeks of proton radiation. During this treatment, I developed a rash on my arms, legs and back - not where the radiation was directly. I was told Flomax could cause this type of reaction. I am now 8 weeks post treatment and stopped Flomax several weeks ago - but the rash has continued. I've been to a dermatologist but they have been unsuccessful in diagnosing the problem. Has anyone else had this problem and if so, how was it resolved.
