Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that reddening,
tingling,slightly swollen,non irritant lips giving a strange feeling are due to some sort of
allergic reaction to some unknown allergen/irritant leading to Allergic
Angioedema of lips..
Noticed only at rest as when you are busy you do not focus over the symptoms which comes more into notice when you are at rest..
However certain common irritants can be certain foods like sea food, nuts etc, medicines, lip cosmetics,soaps,detergents etc..
You should consult an Allergist and get evaluated and he can advise you allergic tests like Prick test,
Patch test, RAST test, Food challenge test to confirm the cause and treat you accordingly..
As of now you should start doing cool compresses over the lips..
Take anti-histamines like Levocetrizine or
Benadryl..
An
Immunotherapy can also be instilled to you by the allergist to reduce the severity and frequency of the allergy symptoms..
Hope this information helps..
Thanks and regards.
