saliva gland swelling

Here it goes:  In February, I noticed two nodules on my face near my ear.  In a matter of days it swelled the side of my face.  A CAT scan showed a tumor in my paratoid and one near the back of my jaw.  My face was swollen and very painful at that time.  I was put on antibiotics and the swelling went down.  I had a biopsy done and it was noncancerous tumor, it was nothing but junk.  It's been seven months and I am still having pain.  I went to the EENT today and am due to have another CAT scan.  The pain is located in my jaw line and where my lower and upper jaw are connect, whatever is there it swells and sometimes my teeth do not touch properly.  There is still swelling.
