<s>[INST] hi, my three years old wake up and had red line on his body. i dont really understand why this had happned, i thought first bed buggs or bites etc. so i kept all the cleanzine in place but more and more red line kind to appear in different areas of body. if he got line on his back, than later on the line disappears and goes somewhere esle on the body, just keep repating the pattern, can you help? what are the red lines and bumps on his body?
