What can this blister/burn be? What can I put on it to heal it?

Thank you for your help!

Question

Hello, While I was listening to programs in bed, I felt a burning sensation in my knee. After checking, I have a large blister the size of a red quarter that feels like burning. There is a small > in the center. It's a little painful.

Hello, It is practically impossible to give an opinion without having first seen the lesion to which you refer (which is impossible here). I therefore recommend that you go to a pharmacy to show the lesion. The pharmacist on duty will be able to direct you to the right product based on his or her observations, or to recommend a medical consultation if he or she deems it necessary. I'm sorry I can't be more helpful at this time. Marie-Laurence Gauthier, pharmacist.
