Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, possibility of allergic disease like
asthma is more in your case. You are taking anti allergic drug and since you have stopped it, you are symptomatic again.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (Pulmonary Function Test).
Possibility.
PFT will also tell you about severity of the disease and treatment of asthma is based on severity only.
You may need need inhaled bronchodilators and inhaled corticosteroid (ICS).
Oral combination of antihistamine and anti allergic drugs is also beneficial.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
