my pain started in my face at the corner of my nose. A large pimple came to a head and popped at the corner of my nostril. My tooth started hurting then it spread to my whole right said of my face, I could not eat or chew for several days. Then my face swelled up on the right side and is very painfull as well as swollen glands on my neck.  I went to the ER on Sat. because I was running a very high fever. They thought it was a sever sinuous infection a and prescribed a pain med and chphalexin 500 to help me get better. Today (Tues) my face is still very swollen and and still very pain full. I was lying down in my bed when all of the sudden puss and blood started oozing out of my gum on the right side of my mouth. I am worried that this is more than a simple sinus infection.
Hi, thanks for your query. The problem may be with your teeth,maybe it is decayed resulting in abscess formation which is Chat Doctor.  Get a radiograph to expose maxillary sinus and the anterior tooth.visit oral and maxillofacial surgeon for this .hope this is helpful.
