Hi..
Can understand your concern..
As per your complain there has been an
allergic reaction due to the drug leading to formation of ulcers / canker sores inside the mouth..
In case if the reaction was severe the painful ulcers formed takes more time to heal and you need to be calm and relax as anxiety and stress can further be damaging for you.
To see the effectiveness of the numbing gels like Bonjela apply half an hour before the meals so that there is no pain and
discomfort while eating.
You can take
Ibuprofen twice daily to reduce inflammation and pain.
You can also take tablets containing Fexofenidine which is an antihistamine and is taken as an anti allergic medicine.
Gargle using half
milk of magnesia and half
benadryl liquid for relief.
Gargle with diluted
hydrogen peroxide solution can help.
In case the inflammation and pain does not subsuide
steroids are
recommended.
Avoid spicy and hot food products.
Drink more of cold water and other cool liquids but should not have citrus nature to maintain hydration and prevent dryness of mouth.
Suck on ice pops relief.
Hopefully in next 7 to 8 days the symptoms will subside but if it does not happen or the ulcers gets large and more painful consult a doctor to get evaluated.
Hope your get well soon..
