You have three major salivary glands, parotid, submandibular, and sublingual. There are also hundreds of minor salivary glands in the mouth, and throat. It can be from what you say or one of many other things, even a recurrence, although not likely, but that's why it's important you should tell the doctor, and be evaluated by them instead of trying to figure it out by yourself. I wish I could say its nothing, even if I thought so, but would not. All the best.
