Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain it seems that your husband is suffering from
Follicular Tonsillitis leading to inflammation and
white spots on tonsils secondary to bacterial infection..
The sores in mouth seems to be occurring eitger secondary to infection or due to side effects of antibiotics..
If it is due to infection it will start resolving once the infection subsides..
If it is side effect of medicine it will resolve after intake of antibiotics is stopped..
He can continue taking antibiotics, do warm saline gargles, and steam inhalation..
Avoid spicy foods, chew one Vitamin C pellet daily and take
Ibuprofen for pain..
For blisters if there is pain gargle with a numbing mouthwash containing Lignocaine, avoid spicy food, gargle with1:1 solution of benadryl and
milk of magnesia and take
Multivitamin supplements..
Hope this information helps..
Thanks and regards.
