Brief answer:
PERICORONITIS.
Hi..
Can understand your concern..
As per your complain the symptoms which you have explained are all due to wisdom tooth.
The swollen gum is not due to tonsils but it is due to infection and inflammation of the gum flap which is covering your wisdom tooth partially and it occurs due to food debris accumulation between your wisdom tooth and the gum flap leading to bacterial infection in that area causing pain, swelling, pus discharge from below the flap on applying pressure ,
lymph node enlargement, throat pain, inflammation in tonsils and at times fever and
fatigue.
Rashes are not seen in case of pericoronitis and it can be due to either some infection or
allergy.
I would suggest you to see a
dentist and get evaluated for the exact cause of the symptoms.
It will most probably be due to wisdom tooth and the dentist will take an IOPAR (x ray) to check whether it should be retained or needs extraction.
You will be given antibiotics and pain killers to relieve pain and reduce infection and inflammation.
Try to keep the area clean.
Gargle with warm saline.
Use antimicrobial mouthwash.
Hope your query is solved..
Thanks and regards..
