hello, it is better to consult a dentist and get it checked, the case needs to be seen clinically before prescribing any medicines. For ulcer, you can add a pinch of baking soda in water and rinse with it. this will give you relief and help in healing of ulcer.

Good Evening. It seems like you have a bacterial infection, most likely an inflamed hair follicle or minor gland. Considering you have fever, you'll most likely need a course of antibiotics. Please see your GP doctor or your dentist. He'll most likely drain it and prescribe you a course of antibiotics and pain killers which should address the pain, swelling and fever within a day or two. Do not apply any balms or heat etc as it'll just make the pain and swelling worse.
