Pain in stomach

The day before yesterday, I drunk a cup of jasmine tea in that evening. Then, my stomach became painful, I felt there is a Hedgehog in my stomach. I went to bed at 11 pm that night, but fell asleep at 1 am yesterday. How painful I was! Parasitic disease? Food poisoning? Germ infecting? However, I'm fine now, the Hedgehog has gone away, I'm very lucky!
