I Did Some MDMA On Saturday, And Ever Since Then

I did some MDMA on Saturday, and ever since then my mouth has been hurting so bad. To the point where I can not eat anything, drink anything. I looked in my mouth and there is white stuff looked like a blister and some yellows stuff. Iv been taking Ibeprofen and ambesol to take the pain away, and it wouldn't last that long so i got myself some Acetaminophen, caffeine, and codeine. Iv eaten more medicine than food today.
