Over the past 5 years I have gotten a slight rash on my left calf at times (not very often); ie mostly was just red in a area and itched alot ...

In the past 2 weeks I have been using a sauna at my local YMCA and I noticed this rash alot more.

Rash - Is a little over a inch in diameter with a smaller white middle and red on the outside.

I'm wondering if this perhaps this was a spot of a 'immunization' or some other shot. And that perhaps the sauna is bringing out some old toxins.

What do you think? or has anyone else experienced something like this before.
