I had mumps last year in August. I got better after taking medicines. But after my recovery I have begun to notice that I feel some reaction in my salivary glands when I eat something sour. It's not painful but I feel something strange. I also want to mention that I had an impacted wisdom tooth. It was also broken. That tooth used to get infected very often causing a lot of pain. Recently the tooth has been extracted. Earlier I felt the reaction in the glands could be because of the tooth. But this reaction to eating sour things continues even after the wisdom tooth is removed. The tooth was extracted about 15 days ago. Please help.
