Blisters and Swollen Taste Buds: What's Going On?

I did that when I was taking leflunomide

I get both of those too sometimes and i’m not sure what causes it at all. I just have to wait for them to go away lol

i’m not sure about the swollen tastebuds so i’m not sure if this will even help, but i get blisters in the inside of my lip and i found out it’s because i’m biting it in my sleep

Sounds like an Allergic reaction
