bite developed into a blister and has grown each day

User Profile
I was bitten on my left ankle on Monday. The bite developed into a blister about 2 hours later and has grown larger each day. It's now a little smaller than a dime and is filled with clear fluid. There's also no redness or discoloration around the blister. I contacted my doctor after I noticed it and they prescribed antibiotics. It doesn't itch and isn't painful. Any assistance on this would be greatly appreciated.

Welcome to e health forum.

It is not possible to provide exact medical advice without a proper physical examination of your lesions.

But based on the available information, you have developed a cellulitis or dermatitis with secondary bacterial infection following a suspected insect bite.

In most cases, such lesions improve with a period of 7 days. If you do not have any disturbing symptoms, you might relax and continue regular dressing the wound and you should see good results in a few days.

If you have any doubts or concerns, consulting a dermatologist will be helpful.
