Please have the soreness at parotid gland checked. I had a stone which I finally passed. If I had not passed it, I would have had to have surgery. My doctor, ENT, who treats my swelling of parotid glands -- fussed at me.. He said if it is sore for more than 24-36 hours I am to call and get appt immediately. I paid the price for now going in earlier. So check with your doctor. My trust mine and feel he is on top of things. I see both an ENt and Rheumie.
