I noticed rashes or bug bites 1/2 around my chest from half front chest to half right back near the bottom of my right rib cage but there is no evidence of bugs on my bed or sofa. There is a little pain of about 4 on the scale of 10 being the worst. There are several rashes around semi-circle of my body the size of a dime, reddish color with a lot of little bubbles of water? Do you have any ideas? I took photo and short video.
