Last Sunday, noon time I was feeling I have been catched some gas problem due to empty stomach, n then felt a very large number of shortness of breath, oxymeter got 92 a single time even, after that I took Pan 40 & Ulgel, then I got some relief, n I got me stay in a AC room, felt better n then had a good sleep at nit, after that I felt some times again that shortness of breath for a very small Amount of time, when oxymeter is fluctuate like 94-99. Otherwise it remain still 97-99 rest of the time. I am taking a Pan 40 each day early morning at empty stomach n also taking Ulgel after the foods. I have not feeling any other symptoms like fever, dry cough or cold or a throat pain. What will be the reason behind it, will I have to worried about it n also any medication or test? Kindly suggest yr valued opinions.. Many thanks!
