Bed Bugs Symptoms, Causes and Treatments. The most common bed bug symptoms are small red bumps or welts that resemble mosquito bites. There are often multiple bites in one area and they are sometimes formed in rows. The rows are due to resting an arm on a mattress seam or other area where the insects are hiding. Bites can occur on any area of the body.
When welts are a sign of a medical problem, they are usually accompanied by other symptoms which provide clues to the problem. Physical trauma such as a blow can cause a welt, and welts can also be caused by allergic reactions, infections, injections, insect bites, and skin reactions, in very sensitive people. For example, in people with dermographism, even a gentle touch to the skin can cause a welt to emerge.
