Hello,
From the symptoms it looks like a blood blister. It is a type of blister that forms when subdermal tissues and blood vessels are damaged without piercing the skin. apply cold compresses, soak the blister in Epsom salt and try to avoid its rupture. If the blister breaks, quickly rinse the area and apply an antiseptic such as neosporin.

If the blister scabs over then the possibility of herpes sore needs to be ruled out. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
