Have red bumps on torso that appeared after I laid down to take a nap. They itch and we have cats so I thought it was flea bites. However, I noticed later they look like little blisters on top and they also hurt a little and don t itch as bad as a flea bite does.i have about twenty or thirty mostly on my right side with a few spring led around my stomach, left side and back. But none anywhere else on my body.
