Im a contractor. 6 days ago I started having a sensation of tiny spiders nibbling on one specific area on my neck , several times i reached around to pinch whatever this critter was. With the exception of a minor itch ans occasional strand of what felt like spider web in my hair i was left with little.bite marks along my collar. Next.to.show were 2 specific fang like marks on my spinal column approximately 6 inchs down from hair line. This has become swollen and has now become a triangle set of bite marks. Ive showered and shampooed severl times but these little bite sensations persist.
