What can I do to get rid of a swollen, stinging red patch?

Hello, thank you for your question, but it is impossible to make an opinion without first seeing the lesions you are referring to, which is impossible here. I therefore recommend that you go to a pharmacy to show the lesions in question.

The pharmacist on duty will be able to direct you to the right product based on his observations, or recommend a medical consultation if he deems it necessary.

I'm sorry I can't be more helpful at this time.
