3 days ago all of a sudden I noticed rash like rough skin just by my mouth on the right side and now it's extending upwards towards my cheek though its still mostly around my mouth. Initially, I thought it was a reaction to something I had eaten so I tried treating it with an antihistamine but it didn't really help. Then I thought it may be dry skin and I tried a hydrating mask but it didn't help either. Now I really don't know what it is because they seem like really tiny bumps that can only be seen under some lights but it can be felt as slightly rough skin. There's been no itching or irritation and its not really red.
