Thomas Jay was taking out the garbage one night outside of his home in Chandler, Arizona, when suddenly he felt a strange pinch on his arm.
That pinch was followed by the most excruciating pain of his life.
Jay had been bitten by a mystery bug-- some kind of cross between a scorpion and a spider. Within just a few hours, tiny circles began to appear all over his arm. Then the circles expanded into massive bruises.
Jay was transferred between multiple hospitals as doctors scrambled to find a safe treatment, not knowing the exact cause. It's now been a few weeks and Jay is stable, but still awaiting biopsy results.
And just in case that story didn't give you nightmares, these GIFs will!
