<s>[INST] i have respiratory issues but doctors.i have been check by others doctors they all tell me its an allegy ,i still insist isnot hat   i got xray saying that they donot see anything i had being trying nasal spray all types they donot help but somtimes it works foe 4hrs then im back to squareone can you tell me [/INST] Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you should consult pulmonologist and rule out asthma in your case. You are having allergy, normal chest x-ray, nasal symptoms, respiratory symptoms etc. And all these are commonly seen in asthma. So consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (Pulmonary Function Test). PFT is must for the diagnosis of asthma. It will also tell you about severity of the disease. And treatment of asthma is based on severity only. You may need inhaled bronchodilators and inhaled corticosteroid (ICS). Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
