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
Hi I do care for your concern.  Swelling and redness is produced due to inflammation caused by insect bite. If I were your treating doctor then I would suggest application of ointment such as Betadine and a tablet of cetirizine would suffice. If you suspect bed bugs then all the linens should be washed with permethrin compounds to get rid of them completely. Hope I have answered your question, If you have more doubts feel free to contact.
