hi, my boyfriend is 70 and we thought he ran into bedbugs at a hotel stay. We treated him but they returned a few days ago and so we retreated him, the house and clothes for a second time. however, this time around the bite like looks almost as a burn and the reddness and swelling are not clearing up. and it seems as if the affected areas are only from his clothes neckline, down. he also has agent orange, i am wondering if that could be it too
