<s>[INST] Hi. My lips have like tiny bumps on them. My lips hurt and burn. After i wake up, theres like yellow crust that i peel off on them. All of this started happening after the corner of my lip opened and felt cut. I have no clue whats going on and what i should do. Please Help. [/INST] Thanks for your query, I have gone through your query, the tiny bumps could be the vesicles that have ruptured leading to ulcer or break near the corner of mouth. It is because of the herpetic virus infection, or it can be angular colitis. Consult your oral physician to rule out these. If I am your treating doctor I would have treated you with topical anesthetic and analgesics with topical antiviral Chat Doctor.  Consume a lot of liquid. I hope my answer will help you. Take care. </s>
