Hi there is a chemical burn or cellulitis on my cheek that appeared two days ago. what do i need to do? it's hurts very bad.

Don't Get Cheeky!!: HEY! That's your face!! Unless you're auditioning for a remake of "It Came From Outer Space," get to a doctor and get it diagnosed and treated NOW!

Antibiotics: If it's cellulitis you may need antibiotics. If burn then local wound care.

Burn or Cellulitis??: Burn or cellulitis might require two very different approaches to treatment ultimately. However, the associated symptom "hurts very bad". I would address with a pain medications such as acetaminophen or ibuprofen. This may also help with the inflammation that is likely associated with either a burn or a cellulitis. In any case you should be evaluated in the next 24-48 hours by your doctor.
