Hello, You may have an allergic reaction or swelling from an infection. Try some anti-inflammatory medication such as ibuprofen or acetaminophen. The antihistamine, Benadryl, may offer you some relief. Try to decide if there are any triggers to this condition. If suffering from an allergy, think of any new foods or dental products you may have tried recently. Stop these products and see if you have relief. Have you started any new medications that may cause a reaction? Look for any insect bites. Eliminate any new cosmetics or lotions. Try to see if you can locate a tooth that might be a source. Is there a bubble on the gum associated with the swelling? Any sensitivity with your teeth? A dental exam would be helpful to make a correct diagnosis. Monitor your symptoms and report them to your dentist. A broken or infected tooth may be the source of the swelling or you may have an impacted wisdom tooth. See immediate care if the condition worsens. You may require a prescription antibiotic. A thorough diagnosis will determine the best treatment for your condition. Thank you for your inquiry. I hope you find some relief and your condition improves.
