Anti-biotic and pain medicine. See your rheumatologist. If you don't have a rheumatologist, get one. This happens to me a lot in the 10+ years since I was diagnosed with sjogrens. I will tell you one (weird) thing I discovered that may/maynot help when your gland has FIRST signs of swelling pain. When in Florida I started having swelling in my paroidid gland (again). While trying to figure out what hospital to go to I ate some very ripe papaya. Strange as this seems my gland drainned. I could even feel and taste (gross) the fluid in my mouth. I then started to massage my gland and all the swelling went down. No doctors visit. Now when I get FIRST signs of pain and swelling my husband runs to the store and buys a papaya and I pig out on it. I have only had to see the doctor for anti-biotics once for a swollen gland since finding the papaya helped open up the plugged gland and drain it with the help of the gentle massaging. I told my rhematologist about this and although he found it interesting he said very little. I have no documented proof that the papaya helped but it has worked for me many times.
