I developed a severe swelling on the left side of my face three days ago. Saw doctor yesterday (two days later), was prescribed augmentin forte (with repeat) and nurofen, and started on these immediately. The diagnosis was an infected cyst beside my nose, an area which is very hard to touch and spreading upward.  The swelling was worse this morning and has reached my jawline. My top gum on the same side is rigid and angry looking and Ive just noticed a small head of pus in the gum over my eyetooth.  I was warned that headache, fever and vision problems needed hospital care.  The question is how long does it take for the above treatment to start working?  And has the infection also caused a dental abscess?  My face is very painful.
Hi, the type of swelling which you are mentioning that it started immediately 3 days ago, and you visited the doctor yesterday it shows that it is some dental infection only which must have arisen from a carious tooth or any trauma on the front tooth. The dentist must have taken an x-ray of your tooth and then came to a diagnosis of infected cyst. The infection will take some time to heal, but only antibiotic is not the treatment, the cause of the infection should be treated it means root canal treatment of the causative tooth or extraction should be done. The pus discharge which is visible is the pus is making its tract to Chat Doctor.
