Your probably NOT a hypochondriac, as if you had that problem it wouldnt just be one issue you are having. You would have multiple issues probably most of the time, and you wouldnt be asking us if you should get treatment, as most likely you would be searching for treatment, and most people who are hypochondriacs dont ask themselfs if they are one, as they truly believe there problems are very real, and would probably take offense to people who tell them otherwise.
Although I am not a expert, most likely you are probably having a problem with a nerve, probably the lingual nerve (I think that is the correct nerve I am thinking of), and a problem with a nerve can cause all kinds of funky sensations. I would see someone about it, you dont want to wait, because if it is something with a nerve, if you wait for it to get bad, then there might not be much that can be done to help
