Allergic Reactions On Skin

Itchy Skin

Sneezing is only one symptom of allergies. Skin reactions like hives, rashes, or bumps from insect bites and stings can cause a great deal of discomfort. Allergic reactions like itching can escalate quickly, so it is important to be prepared.

Many skin reactions are harmless, but if you are worried, especially if accompanied by other symptoms, consult your doctor.

Hives

This itchy skin condition is a common allergic reaction caused by the release of histamines and other chemicals into your bloodstream. Seek relief with creams or sprays that can soothe your skin and prevent further irritation. Symptoms of hives can include:

  • Itchy, red or skin coloured welts

  • Welts that “appear” white when you apply pressure

  • Swelling or bumps

Rashes

Rashes can be bothersome and unsightly. Many things can cause rashes, such as an allergic reaction (including a reaction to medication), infection, overheating, or irritant contact. Try to avoid scratching or aggravating skin. Symptoms of rashes can include:

  • Redness

  • Itchiness

  • Swelling or bumps

  • Oozing or blisters

  • Flaking or scaling

Insect Bites

When insects bite or sting your skin, your immune system reacts by causing redness, swelling, itching or pain. A topical cream can provide fast, effective relief of itchiness and pain caused by insects. Symptoms of bug bites or stings can include:

  • Redness

  • Swelling

  • Itching

  • Tenderness

  • Blistering

WHICH ITCH IS THIS?

Nature Itches

When spending time outdoors, it is important to be aware of insects and poisonous plants that can cause itching, pain, and allergic reactions. A few common sources of outdoor itches include:

  • Poison ivy

  • Poison oak

  • Poison sumac

  • Mosquitos

  • Blackflies

Sun Rash Itches

Too much sun can cause a blistering rash that demands relief. This red, itchy rash appears as a result of sensitivity to sunlight and is most common on the upper chest, neck, back, and the back of arms.

Everyday Allergies

While a runny nose could be the sign of an impending cold, if your nose and eyes are also itchy, it is likely allergies. Be prepared; over 47% of Canadians suffer unexpected allergic symptoms each year*.
