Three strange allergies you’ve never heard about

The world is a weird and wonderful place. In every corner of the globe, there is something unique that you’ve never even thought about before. It makes life more interesting – there’s always something new to discover and learn about.

And that goes for allergies too. Everyone knows about hay fever or peanut allergies, but how about some of these rare conditions? They aren’t your usual allergies in that they aren’t certain products or food. Let’s dive in!


This is a reaction to the pressure put on the skin when you touch it. As your finger runs over your skin, it leaves inflammation and welts in its path. It’s earned the condition the name ‘skin writing’ or – to use its proper term – dermatographism.

It is very rare, affecting 2-5% of the population. Thankfully, it’s not a life-threatening condition, and most of the inflammation seems to go down within 30 minutes. Symptoms come from histamine being released by mast cells on the skin. Histamine is the cause of many other allergies – such as hay fever – meaning dermatographism can also be treated with the same anti-histamine medication.


Clearly no one in the Beach Boys vibratory urticaria. This condition makes you sensitive to vibrations. Like dermatographism, your skin will react with red, itchy blotches. If you have been mowing the lawn, for example, you would likely see it on the hands.

Other symptoms include headaches, blurry vision, and fatigue. The vibrations don’t have to just be from the lawnmower; anything that causes you to vibrate might bring out the reaction – riding a bike being another example.

Your own child

In some rare cases, mothers of newborn babies can’t even hold their child. It’s a condition called pemphigoid gestationis and can appear during the second or third trimester of pregnancy. Again, it is a skin condition, with itchy patches and blisters on the body. It can happen while the baby is still in the womb, or – as in this story – after the baby has been born.

It can be distressing for young mums who just want to hold their child. Some estimate it to occur in 1 in 50,000. Thankfully, it isn’t a true allergy and doesn’t last forever. For many mothers, it fades over time. So it isn’t a lifelong condition.

And those are just a few weird and wonderful reactions. While none of these were life-threatening, you should always be careful with any allergies. Always talk to a professional for an accurate diagnosis and advice on how to best live your life.
