Acute stomach cramps, this is crazy;;

Acute stomach cramps and gastritis… I really thought I was going to die.
Dental root canal treatment is at a child's level...

I, who had never been to the emergency room in my life, went to get some medicine.

How do I hold out when I run out of medicine,,,? ;;;;;;

The pain felt like it was being stabbed in the forehead and lasted for 30 minutes to an hour…
Can I just take an antispasmodic from the pharmacy? ;;;;

I'm scared of food right now, what should I eat?
Those with experience, please give me some advice ㅠㅠㅠㅠ
