Question ?: Your post did not include a question. But from the facts you listed, it appears that that wisdom tooth needs to be extracted. Please call a local dentist or oral surgeon for an appointment.

See a dentist: When wisdom teeth cause problems, they need to come out. If you are experiencing pain, swollen gums, lymph nodes and it does not go away or if you find it difficult to open your mouth, you should see a dentist for evaluation, x-ray and wisdom teeth removal.
