Answer:
You can try to treat this yourself. Wash the area with soap and water daily which is the ideal anti-bacterial you can use. Pat the area dry then, put some bacitracin or neosporin ointment over the blister/scab area and put a bandaid over it. This should help clear it up in about a week. Common sense should tell you that if it gets worse and worse, the redness or swelling increases and there is a lot of white pus seeping from the wound, then it is time to see your physician.

Answer:
I hardly think a lesion on one's foot has anything to do with an STD.

It is uncommon for a lesion to become infected after forming a scab.
If you are distressed, see a physician.
