Can a spider live in your neck?

While it's extremely unlikely for a spider to live in your neck, they can occasionally crawl onto people and may even be found in unusual places. Spiders are not parasitic and do not burrow into human skin or tissues. If you feel something unusual on your neck, it's more likely to be a harmless encounter rather than a spider living there. If you're concerned about any unusual symptoms, it's best to consult a healthcare professional.
