Hi..
Welcome to HEALTHCARE MAGIC..
As per your complain the symptoms of swollen lips which started with tingling and itching with redness and swelling seems to be most probably due to
allergic reaction caused due to conditions like bug bite, allergy to any food or medication etc..
It is therefore leading to Allergic
Angioedema of the lips along with inflammation..
Nothing to worry as it will be resolved soon, although can take about a week to resolve completely..
You should take anti-allergic medicines /anti-histamines like
Diphenhydramine [benadryl or fexofenadine[allegra] or levocetrizine for faster resolution of the swelling.
Take anti-inflammatory painkiller medicine like
Diclofenac potassium or
Ibuprofen.
Do cold compresses over the lip.
Apply calamine lotion to relieve irritation.
Do not apply pressure, suck or bite the lip..
Drink plenty of water..
Hope this information helps..
Thanks and regards..
