I'm a 30 year old Male and am having problems since last 3-4 years,very first time before 4 years i took very chill cold drink with chicken fry(chicken was very oily and oil not good),that time i slept in night.After few hours at 4-5 am in early morning i felt problem while breething,i was not able to breeth,so not slept that time.That day i was not able to sleep,even not able to walk due to problems in breething and felt very tired due to this.Even feeling like a patient ,after that i took normal medicines from doctor and was normal immediately after same day.After that same problem occurs frequently for some days.I am not sure about this problem.My doctor told me its a alergy type problem.But when this problem occurs i having toilet problem,its not normal and my stomach is little heavier.Please suggest me what i can do for this?what precautions needed to avoid this problem??
Is it stomach gas problem? or any other breething related issues?
