“Most bug bites and stings can be safely treated at home with topical medication, such as hydrocortisone cream or ointment, or an oral antihistamine to reduce the itch,” said board-certified dermatologist Margaret E. Parsons, MD, FAAD, associate clinical professor of dermatology, University of California, Davis. “Sometimes, however, a bug bite or sting could turn into something serious, particularly if you have been bitten or stung by many insects at the same time.”
Dr. Parsons advises going to the emergency room immediately if you experience any of the following symptoms after a bug bite or sting:
- Difficulty breathing
- The sensation that your throat is closing
- Swollen lips, tongue or face
- Chest pain
- A racing heartbeat that lasts more than a few minutes
- A headache
- A red, donut-shaped or target-shaped rash that develops after a tick bite: This could be a sign of Lyme disease, which should be treated with antibiotics.
- A fever with a red or black, spotty rash that spreads: This could be a sign of Rocky Mountain spotted fever, a bacterial infection carried by ticks, which should be treated immediately.
“Although most bug bites and stings do not turn into a severe or even fatal illness like Rocky Mountain spotted fever, it’s important to pay attention to your symptoms,” said Dr. Parsons. “If you feel tired all the time, you have a headache, fever or body aches, or you develop a rash after a bug bite, see a board-certified dermatologist immediately.”
