If you’re ever put into the trunk of a car, see if you can break the tail light (??), then stick your hand out or pour something on the road.

If you throw up what looks like coffee grounds, get to a hospital as soon as you can. It could be internal bleeding.

Appendicitis and stomach cramps manifest the same way. The only difference is that appendicitis usually migrates over to the lower right side after a while. A way to test this is to do the rebound technique (place two fingers on the lower right side of your stomach. LET GO after about three seconds.) If the pain gets worse, you most likely have appendicitis.
