Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of acute worsening of asthma is more in your case.
You are having
allergy and you are not taking inhalers regularly, so worsening of underlying asthma can cause breathlessness,
chest pain and
tachycardia (
rapid heart rate).
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (Pulmonary Function Test).
PFT will tell you about severity of the disease and treatment of asthma is based on severity only.
You may need regular inhaled bronchodilators and inhaled corticosteroid (ICS).
Oral combination of antihistamine and anti allergic drugs is also beneficial in your case.
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.
