Thanks for writing to us.
From your description the red spot seems to be due to czema or dermatitis- may be allergic in origin. Please do not worry as most of such rashes are self limiting and subside on applying 1% hydrocortisone
ointment. Do not itch or scratch on the area to avoid any infection.
I hope this information has been both informative and helpful for you.
