Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itching in the underarms along with swelling of lips seems to be due to
allergic reaction only..
It can be due to any food or drinks consumed or any medication taken..
It can also be due to any insect bite or due to exposure to any irritant or allergen like any soap, cosmetic etc..
I would suggest you to take anti allergics like
Allegra or
benadryl..
You can also do cool compresses over the lips as well as in the armpits..
You can also apply a steroid ointment over the bumps..
These remedies will help in relieving the symptoms..
You should also consult an Allergist and get evaluated and he can advise you allergic tests like
Patch test, RAST test, food challenge test etc to rule out the exact cause of the reaction and you should avoid exposure to the allergen to avoid occurrence of allergy symptoms..
In case if the symptoms worsen injectable
steroids can be given along with oral anti allergics and steroids for faster relief..
Hope this information helps..
Thanks and regards.
