Another of the triggers of Fibromyalgia fall more into a miscellaneous category with one thing in common. This is having your head and neck in extension for a prolonged period of time. In English, this means having your head looking in an up position (as if you were watching fireworks or an air show).
There are a number of ways this can happen and more often than not they lead to a flare (for people with Fibro), or these can trigger the onset of Fibro.
Dental surgery, where your head is in this position while the Dentist is working on your teeth.
An exercise class where you are told to stretch your neck in different positions.
The Beauty Salon, where your head is being washed in the sink and, of course, your head is pushed back and upward.
A Chiropractic adjustment where your head and neck are twisted into that same position.
A physical therapy session, where again, the therapist is having you do stretches that cause this extension.
These are some of the situations where this might arise and it is best to avoid having your head in this position, at all costs. Dentists, Chiropractors, Physical Therapists, Beauticians can easily modify what they do to take this into account, but it is up to you to be aware of it and inform the person that you need to avoid that position.
