Yesterday morning I woke up and had no bruise on The back of my hand , but by early afternoon a bruise started forming! I don t recall hitting anything, but by dinner the bruise is the size of a dollar coin, it is a deep purple with a perfectly round white spot in the center! It doesn t hurt until I push on the white spot, but if I just run my finger over it, that spot is numb. Curious if it s a bug bite of some kind! Please help! From Curious
