Hello and Welcome to Healthcaremagic.
I will try to the best of my ability to help you with your concern.
The symptoms you mention in query are pointing towards a condition known as
canker sore ,which are responsible for swelling ,burning sensation and numbness . There can be many reasons for occurrence of canker sore like stress , irritation from hot spicy and acidic food , irritation from sharp ent of tooth braces or other dental appliance and vtamin deficiency like
vitamin B12 and folic acid .
Usually canker sore go away by its own in few days without any treatment.
I would suggest you to :-
- Apply cold pack to swollen lips .
- Do warm saline rinses 2-3 times a day .
- Apply colgate oeabase gel for burning sensation.
- Start taking Vitamin B12 and
folic acid supplement for at least 10 days.
- Take advil (if not allergic to ibuprofen) or tylenol for pain and swelling.
If condition doesn't get better in a week then consult oral pathologist for proper diagnosis and to rue out causes like
diabetic neuropathy or dryness of mouth .
Doctor may prescribe corticosteroid ointment , antibiotics or
sucralfate.
I hope it helps.
Thanks
Dr Harry Maheshwari
