I believe I was bitten by bed bugs this past weekend. I have a small patch of red swollen bites. They itch and hurt not only in the immediate area (below my arm on my back) but in the surrounding area as well. Since the bites, I ve experienced nausea, feeling lightheaded and I ve lost my voice due with a throat that feels itchy (as opposed to sore). I m not sure if these symptoms could be related or are a coincidence. I should also tell you that I have a severe allergic reaction to stinging insects and was treated for years as a child to build up my tolerance to bees, yellow jackets, wasps, etc.
