After developing severe pain from muscle stiffness and cramps, the victim of a black widow spider bite will experience: flulike symptoms.
Black widow spiders usually  found in Mexico, the southern United States, and Canada. They reside in low-lying webs near swimming pools, in wood piles, garages, grills, and barbecues. Between April and October, the majority of bites happen in suburban and rural locations. When their webs are tampered with, these spiders often bite. Bites to infants and young children can be more dangerous than bites to adults.
After being bitten by a black widow spider, one may have painful swelling around the bite.   Additionally, individuals can get stomachaches, cramps, and muscle spasms. These symptoms may worsen, up to 12 hours after you have been bitten. It may take a few days or weeks before all the discomfort goes away.
