For the last few weeks every couple of days in the late afternoon I get two itchy red lumps appearing next to eachother in a random place on my body, some go in a day, some go in a few days and leave a small scab on top, I have used flea powder and bed bug spray but I am still getting them, heres what they look like http://tinypic.com/r/2rctxu8/9 (more red and noticeable in person)
