As warmer spring days draw us back outdoors, learn what signals a problem from bug bites.
As the weather warms up and we all start spending more time outside, whether enjoying family walks, spring sports, or watching the kids play in the backyard, we also start encountering more bugs. Most of the time, a bug bite is nothing to worry about. However, sometimes, a bug bite may not be that simple, and you may notice an unusual reaction. When you experience a bad bug bite, there are signs that it’s time to visit your local emergency room and seek medical help.
Even though most bug bites are not preventable, if you know you are going to be near bugs, it is recommended to wear bug spray.
It is important to note that bug bites are not just a cause of concern during the warmer months and when you are outside. You or a loved one may encounter an insect at any time of the year, even inside your home, as some insects do not hibernate.
Signs it is Time to Go to the Emergency Room For a Bug Bite
- Fever: A fever is your body’s defense against foreign substances. A fever paired with chills means your body is fighting something internally.
- Swelling: Moderate swelling with a bug bite can be expected. However, if you begin to experience swelling that moves outward, it may be a sign of an allergic reaction or infection spreading. Also, swelling paired with blisters may be a sign of venom in the body from a bite.
- Redness and Puss: Bug bites are known for itching, but it is important not to scratch! We know, easier said than done. But, scratching a bite can cause an infection, creating redness and puss or even a red line outlining the wound site.
- Oozing Liquid from Bite: If your bite has crust or an oozing liquid, this may be a sign of a more serious condition like impetigo.
What Can Happen if You Do Not Seek Treatment For a Bad Bug Bite
- Allergic Reactions: As the reaction to a bug bite worsens, you may discover you are allergic to the bug that bit you. Spreading pain, swelling, and trouble breathing are signs of an allergic reaction. Without the proper care in an allergic reaction situation, anaphylaxis may set in, causing symptoms to react over the entire body.
- Serious Complications: Allergic reactions are not the only possible outcome of a bad bug bite. There are other troublesome issues. Some bugs have poisonous venom that release into the body upon contact. Also, bugs can carry fatal diseases. It is important to listen to your body, and if you are experiencing symptoms, you must seek medical attention immediately to avoid serious medical conditions.
