Thanks for your question on Healthcare Magic.
I can understand your concern.
You are having
allergic reaction for sure.
Symptoms like swelling of lips, rashes after eating certain food and drug (
ibuprofen) are characteristic features of
allergy.
In my opinion, you should consult allergist (allergy specialist) and get done detailed allergy testing to identify the causative allergens (food items, drugs, dust, pollens, mites etc).
You should avoid all the allergens to avoid symptoms.
You should also take combination of antihistamine (levocetrizine or
fexofenadine) and anti allergic (
montelukast) drugs for symptomatic relief.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
