DEAR DR. GOTT: Recently, after being on my feet for up to 10 hours, I got a rash around my ankles and the tops of my feet, and sometimes it goes up my legs. Tender to the touch, it is more noticeable the longer I am on my feet. It disappears after a few days if I’m not on my feet constantly.
DEAR READER: Common causes of foot rash are dry skin, heat exposure, fungus and spider-vein itch. If your feet are dry, rub them with a lanolin-based cream. If heat could be the culprit, change to footwear such as sandals or canvas sneakers, and wear light cotton socks. Fungal infection might be treated with a topical medicated product or a trip to your physician for a prescription. Spider-vein itch is treated with elastic stockings and alternative remedies.
