5. Stomach Cramps (Black Widow)
Black widow bites may also cause stomach cramping. In fact, this is one of the reasons that people go to the emergency room after receiving a black widow bite, because the stomach cramping can be so intense that you feel as if you’re dying. If you have ever had appendicitis or a ruptured appendix, the pain is similar.
Stomach cramping is definitely something that you should be looking for if you were just bitten by a spider that you think might be a black widow, but the best way to tell whether or not it was an actual black widow bite is to look at the other symptoms as well.
There are some instances where the stomach cramping doesn’t happen or isn’t pronounced enough to give you an indication of a serious spider bite, but they are rare. If you experience this cramping, then you may want to visit the emergency room.
