I used a mild soap and tried to keep it dry and avoid friction like you suggested. Took a week and a half but it's mostly faded away now. Thank you for your advice.
Hello,
Without examination,confirmation of a diagnosis is tough but it can be contact dermatitis,rash due to friction rub with clothes, dermatitis (atopic, contact, allergic),excessive sweating causing sweat dermatitis or underlying infection (bacterial/ fungal).
You may try calamine lotion on the rash.You should also maintain hygiene and try to keep the area clean and dry, wear loose-fitting cotton clothing. Also use an antibacterial soap or mild soap like dove.Avoid any kind of cosmetics.You can also use a barrier cream with zinc oxide paste or a mild steroid cream like dermacort on the rash. If the rash is itchy,you can take some antihistaminic like benadryl or Claritin.
If the rash persists then it will be best to get it evaluated from a dermatologist.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.Warm regards.
