Insect bites
Insect bites are a common occurrence, especially during the summer months when insects are abundant. They can cause itchy skin, irritation and pain. In this blog post, I will discuss the different types of insect bites, their symptoms, and how to treat them.
Types of Insect Bites
There are many types of insects that can bite humans. Some of the most common include mosquitoes, ticks, fleas, bed bugs and spider bites. The type of insect that bites you will determine the severity of the bite and the symptoms that you experience.
Mosquito Bites
Mosquito bites are probably the most common type of insect bite. They are usually itchy and may cause a small bump to form on the skin. In some cases, mosquitoes can transmit diseases such as West Nile virus or Zika virus.
Tick Bites
Ticks are small, blood-sucking insects that can attach themselves to humans and animals. They can transmit diseases such as Lyme disease and Rocky Mountain spotted fever. Tick bites can be painless, but they may cause a red rash and flu-like symptoms. An early sign of lyme disease is the presence of a “bull’s eye” rash within 3-30 days of being bit. If you’ve been bit by a tick, contact RxToday.ca as soon as possible to speak to a pharmacist even if no symptoms are present.
Flea Bites
Flea bites are usually found on the lower legs and feet. They are itchy and may cause a small red bump to form on the skin.
Bed Bug Bites
Bed bugs are small, nocturnal insects that feed on human blood. They are usually found in bedding and furniture. Bed bug bites can cause itchy red welts that may be arranged in a line or cluster.
Symptoms of Insect Bites
The symptoms of insect bites can vary depending on the type of insect that bites you. Some of the most common symptoms include:
- Itching
- Redness
- Swelling
- Pain
- Burning sensation
- Numbness
In some cases, insect bites can cause more severe symptoms such as:
- Hives
- Difficulty breathing
- Swelling of the face or mouth
- Anaphylaxis (a life-threatening allergic reaction)
Treatment of Insect Bites
Most insect bites can be treated with antihistamines, topical corticosteroids, pain reliever or simply applying a cold compress to the area.
