6 days ago I woke up with the feeling of a rock in my stomach. I didn't feel great but went about my day. Around noon I had no appetite and slept for the rest of the day. Severe diarrhea and exhaustion began that night and continued for 5 days (and no appetite remained). I felt so much last night and ate a meal like a normal person and totally better today (day 6) until - boom I felt the rock in my stomach after my first somewhat solid bowel movement. Im back in bed, uncomfortable again.

Anybody ever experience anything like this? Is it a virus or something I should be seen for?
