A Rash On The Back Of My Thigh, Very Itchy, Pus Filled. What Is The Treatment?

Hi there, 5 days ago, I've noticed a rash on the back of my thigh, very itchy, so I put sudo cream, didn't do anything, I put betadine, no changes. So I put apple cider vinegar on Sunday. Monday morning, it turned into blister with black dots and pus filled, so I thought that works. Been doing it tha last 3days, an still racking my brain what could it be or where I got it from. It is still itchy, but I try not to scratch it but it is sore. Should I have just seen the doctor, I don't know if I made it worst by using acv. Any inpu would help. Thank you.

Hi, thanks for your query
The rash on thigh could be due to insect bite or boil or fungal infection.
It seems apple cider vinegar caused irritant dermatitis leading to formation of blister and collection of pus.

Don't rub or scratch it otherwise it will rupture and may get infected further.
You may apply a steroid and antibiotic combination.
Take an anti histamine daily for a week or more.
You may take an oral antibiotic by prescription from a doctor.
It may take 2-3 weeks to settle.

Hope this input helps you.
