Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain sore
palate and dry tongue can be due to change of your eye drops causing oral side effects and soreness of mouth can be secondary to
dry mouth due to incomplete saliva in mouth..
You should consult an Oral Physician and get evaluated so that he can also look for other causes of the sore and dry mouth like
Salivary gland disorders, oral infections like Thrush, stress,
mouth breathing etc and treat you according to the cause..
As of now you take symptomatic treatment like sucking tart candies and chewing sugar fee chewing gums as it stimulate saliva flow..
Drink plenty of cool water and suck ice.
Artificial saliva drops are also available in the market and can be instilled in mouth for relief from dryness..
Avoid spicy food and maintain a proper
oral hygiene to prevent secondary infections..
Hope this information helps..
Thanks and regards.
