my wife went to walk about 12 miles. She put on bug spray with deet. When she was done, she had a red ring around her leg, right where the socks gather above her ankle. It had rained and she suspected that the rain washed all of deet into her sock and made it concentrated enough to cause the red rings around her leg. Any other reason why this would have happened. She did not get bitten on both legs or anything. Thank you.
Hi, As per your query your wife have symptoms of red ring rash on the leg. Need not worry. I would suggest you to keep this area clean and Chat Doctor.  You should avoid touching or pricking rashes. If condition doesn't get better than consult dermatologist for proper examination. Doctor will examine physically along with blood test and sample for lab test. Doctor may prescribe immunosuppressants, antibiotics like clindamycin, anti-inflammatory or antifungal. Doctor may also prescribe benzoyl peroxide ointment. Hope I have answered your query. Let me know if I can assist you further.
