Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from viral infection causing
tonsillitis and mouth ulcers..
It can also be due to
throat infection leading to inflammation inside mouth and causing mouth ulcers or canker sores..
I would suggest you to consult an Otolaryngologist and get evaluated and a throat swab culture and also Oral swab culture can help in diagnosis and treatment can be done accordingly..
As of now you should take anti inflammatory painkiller like
Ibuprofen..
You can gargle with warm saline solution..
You can chew a Vitamin C pellet daily..
You can avoid spicy and hard foods and take a soft bland diet with plenty of fluids..
For pain in mouth gargle with steroid mouthwash and even a course of tapering dose of steroids and a steroid shot can be given to you for relief..
In case if viral infection is diagnosed
antiviral medication like
Acyclovir, Valacyclovir can be given for help..
Hope this information helps..
Thanks and regards.
