Talk to Gastroenterologist on Stomach Issues

15 days before, i had severe stomach ache that i wasn't feeling relief even after taking medicines so i had to rush to emergency and doctor applied drips. doctor said its because of baqra eid. then yesterday morning, as soon as i woke up and opened me eyes, i got severe pain in my kaleje ki side i.e. upper middle part of stomach that i wasn't able to breathe properly. today morning, as soon as i woke up, i got severe pain in my left kidney side that i wasn't even able to stand properly. from today afternoon, i got this irritating thing, even when i pass urine i feel like more urine is coming but actually its not. i am tired of all this. from one month i am having loose black motions. iron tablets might be the reason but now i am not taking those. please please help.
