6. Sweating (Black Widow)
Sweating is another symptom of a black widow spider bite. This is something that is very unique to the black widow bite, and it is something that you can easily use to identify which type of spider bit you. That’s because neither of the other two dangerous spiders on our list has this particular symptom, nor do any of the other spiders that you might encounter in North America.
In addition to sweating, or sometimes in place of it, you will notice that you are producing more saliva than normal and have to swallow a lot. These are pretty unique symptoms among all illnesses, but you can easily identify the black widow bite by this particular symptom combined with any of the others that are on this list.
For example, if you have pain or burning combined with sweating or salivating, then you were probably bitten by a black widow.
