hi, i am Rajdip, male, 23. For last 10 months i am experiencing that i need to breath often whenever i am sitting or standing up or lying at bed, more like as if i am breathing manually. it occured first after i vomitted 4 times as i had acidity and from next day i am experiencing this. Its not like that i am facing this problame everytime, whenever i am busy of doing some work in my pc or watching tv, i cannot realise this but whenever i start thinking about this it begins. My doctor said its happening as i have allergy in cold and dust. A homeopathic doctor told me that as i am a bit healthy and a bit obese too, its happeng for that reason. I am a smoker, i somke 3-4 cigarettes a day which is not so much in my opinion. af anyone feels the same, please share your experience.
