Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain sudden itching or irritation of tongue followed by lips seems to be most probably due to
allergic reaction and it seems that you are continuously exposed to some unknown allergen leading to itching or irritation of tongue and lips..
It can be due to things like any food or medicine, any lip cosmetic, or any environmental allergen..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and allergic tests like
RAST test,
Patch test, food challenge test can help in diagnosis and treatment can be done accordingly..
On ce the allergen is diagnosed try tp prevent exposure to allergen to prevent the symptoms..
You can take anti allergics like Levocetrizine or
Benadryl for relief from symptoms..
In case if there are recurring symptoms an
Immunotherapy can be instilled to reduce the severity and frequency f allergic attack..
Hope this information helps..
Thanks and regards.
