Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itchy growth over the palate that keeps recurring can be due to causes like
allergic reaction to any food or medication, bacterial or viral infection etc.
It needs a proper evaluation and examination of the exact cause of the sore and can be treated accordingly..
You can be advised a swab culture of the sore to check for infections while a
blood test can be done to rule out for allergies so that the exact cause of allergic reaction can be ruled out and treated accordingly..
In case of infection a course of medication like antibiotics or
antiviral medications depending upon the exact cause can be helpful..
In case of allergic reaction anti allergics like Levocetrizine or
benadryl and
topical steroid ointment can help..
Avoid exposure to the allergen once it is ruled out can help in preventing recurring symptoms..
Hope this information helps..
Thanks and regards..
