red rash above ankle after walking

This is really stange...but after walking for several hours, I develop a red blotchy rash right above my ankles that feels like sunburn on both legs.  This has happened many times, usually after shopping or being on my feet for long periods of time.   I have not changed any lotions, deteregents or other products that might be the culprit.   It seems to only occur after long periods fo being on my feet.  There is no swelling.

Thank you.

Hello,
For these symptoms, golfer’s vasculitis rash should be ruled out. It often starts above the sock line and makes red patches and splotches up the calf. In that case, taking bath with cold water after staying in the sun or applying cold wet towels may help.

You may apply calamine lotion and cool compresses on the rash. It may help. You may also take some OTC antihistaminic like Benadryl or Claritin.

Please see your dermatologist if the condition does not improve.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
