Thank you for posting your query at DoctorSpring.com
I can understand your concern.
This seems to be erysipelas which is a bacterial infection of the skin and soft tissues. You urgently need to see a doctor who can prescribe you a course of oral antibiotics. You need to take them on an immediate basis. If left untreated this could increase and could cause swelling of the whole face. You can take an anti histamine like Allegra to reduce the inflammation.
Please let me know if you have any queries.
