Welcome to HCM!
On reading your query it looks like that you had an infection after eating that food, it has subsided in some form that you don't have any pain while eating food now, but still the stools are dark and sticky.
I think you should go for an antibiotic course, like cefpodoxime
combination, along with Omeprazole
20 mg and domperidone
, twice a day. had I been treating you I would also like to see an ultra sound
abdomen to check if everything is ok.
Stop spicy food and reduce the oil in diet for some time, this will help in early recovery. go for simple non spicy and semi solid diet--- like khichdi, dalia, semolina etc.
You may need a stool test to check if the dark color is due to blood or some other pigment, this will make things more clear.
so, please see a doctor
hope the reply is helpful
ask more question if there is any problem
Get well soon
