Strange coincidence after rads?

Hi,

I was part of the Sept group doing radiation. I had 4 weeks radiation to my left breast. I did well and finished Oct. 2.

On Oct. 4, I started feeling an uncomfortable sensation in my right foot. Primarily big toe, but other toes as well. Looked at my foot and it was turning very red, almost purple. Only happens when sitting still. Once I move, back to normal color. I have never had any circulation problems in my life.

Went to podiatrist to start. Felt pulses, checked toes for circulation....all good. Felt it is Reyanuds Phenomenon. I am very uneasy about the whole thing and am going to another doctor, this time vascular.

I googled and read and no where does it say radiation can cause these issues. Anyone ever had a strange unexplained thing happen after rads? I think it is just coincidental, but so frustrated as I am dealing with anxiety from the whole breast cancer diagnosis so I am waiting for something bad happen.
