burning sensations anxiety/stress ??

Im generally a relaxed person who doesnt get stressed - so now for 8 wks I have burning sensations throughout my legs mainly feet (top) and shins and also my groun area - which is also tender to touch - I touch it burns.

I have a mortal fear that I picked up a viral infection (such as herpes) and look for every abnormality / pimple/ coldsore/rash and anything else - Just the thought or seeing another symptom gets the palpatations going sometimes causing coughing that could lead to vomiting.
I have also noticed if I now get stressed for what ever reason my feet/shins/groin flare up and feel as if they are burning off. -

Is this common? could this be a nervous / anxiety thing? and any ideas on how to stop this??
calming down does help - until I see the next problem.

would love anyone to offer some advise/comments on this problem - anxiety/stress could this cause these problems
thanking you in advance - hopefully hear comments soon
