Itchiness is just one of the symptoms that come with fibromyalgia. And if you’re one of those who suffer from this, you know that it’s both stressful and irritating.

Read on to find out.




Possible Causes of Fibromyalgia Itching

No one really knows the exact reason behind itchiness in fibromyalgia. However, there are some theories that could explain it:

  • Some people believe that the itchiness has something to do with the accumulation of heavy metals through diet. According to them, this has also contributed to some other fibromyalgia symptoms. One of these is itching.
  • Others however argue that itching has to do with formication. This is a disorder wherein your brain will imagine things that are not really there. In this case, it will imagine a feeling of itchiness, even if there is no itching present.
  • Experts in the field of chronic itching believe that hypersensitive nerve fibers sending wrong signals to the brain is the reason behind fibromyalgia itch

What Do Antihistamines Do?

Antihistamine is a type of drug designed to block the body’s natural response to allergy. When your body is exposed to allergens, it will start to release histamine. This is a type of chemical that will encourage the body to release fluid from cells. This will also trigger stuffy nose and cell inflammation. All these can lead to a feeling of itch, which is usually due to irritated skin cells.

Your body’s immune system helps to keep you protected against dangerous substances. The histamine released from your body clog your nose and respiratory system. However, often times, your body ends up releasing histamine because it mistakes harmless substance as dangerous. Antihistamines block the body’s release of histamines to allow you to breathe comfortably and prevent itch.

However, as fibromyalgia itching is not likely caused by histamines, antihistamines may not always work for relieving fibromyalgia itch.

  • I use topical and oral antihistamines, ie, Benadryl. It has provided a lot of comfort from the fibro-itch. So I say Yes!

  • I take four to six piriton a day, due to asthma and other allergies and I don’t see any relief from fibromyalgia itching at all. Unfortunately I haven’t found anything else that works for me yet.

  • My itching happens when I lay down at night. Bendryl will help and Zyrtec during the day. Totally staying away from gluten and sugar and dairy mostly gluten absolutely helps.

  • I use strong cortisone cream, but that doesn’t always help, so I have found that Benadryl really helps, but it does make me drowsy. I would rather sleep than itch! I have also taken extra Neurontin that usually helps after awhile. Maybe I’ll try a less strong antihistamine during the day. I’ve always felt it’s our hyper sensitive nerve endings that cause the itching, just like they cause so many other things. Maybe they will find the answer soon.
