Hi. A few days ago I had itching on my left rib cage area. Got home & looked at it in the mirror and it's a red, almost perfect circle the size of a dime with what appears to be 2 puncture woulds in the middle. I then got one on the back side of my left leg. Last night a spot on my stomach started itching and, after scratching a little, it is now the same dime-sized red, itchy circle with what looks like 2 puncture marks in the center. A few hours later I had one on the right front of my rib cage. All 4 are still red and itchy and have the same puncture holes about 1/8" apart. I've looked at bug bites and can't identify with any of them. Any clue? Thanks!
