What's the definition of double crush? I've been told I have it but I also had tendinitis a few decades back and still suffer from that too I believe. Can one have both double crush AND additional compressions at the elbow and/or wrist?

I'm thinking of taking a trip to the Mayo Clinic to get diax for my multitude of issues to see if there is anything other than the TOS surgery I can do. I have Hypermobility, perhaps Fibromyalgia (yes, dxed), degenerative disk disease, pec minor syndrome, and perhaps the tendonosis or whatever is affecting my arms and elbows in addition to TOS. Has anyone here been to the Mayo Clinic for diagnosis? Don't worry; I wouldn't consider doing TOS surgery there.

thx!

A double crush is compression of the nerve at multiple locations. Effects of the compression at the lower area is exaggerated due to the other higher up compression.

I did a little online research on this, and now I want to know if my bilateral carpal tunnel is possibly double crush. . . .as I have cervical issues which seem to make it (the CTS) worse on some days. . . .

Thanks for asking this question, as I had never heard of this before.

They call it a crush, but symptoms could be from impingements, adhesions or just sticky fascia.
If it tends to come and go somewhat it could be due to trigger points.

Has anyone had or heard of an MRE? The article below is from Mayo.
I and probably many of us with long standing TOS suffer from myofascial pain as part of or in addition to TOS. Is hypertrophy considered muscle hardening and loss of elasticity?

"...magnetic resonance elastography, or MRE, can provide images of the affected muscle with clarity and insight not possible with magnetic resonance imaging, or MRI. While an MRI uses a magnetic field and radio waves to create clear and detailed cross-sectional images of the body's internal tissues and organs, an MRE measures the elasticity of tissue as it is gently vibrated.

"Additional research is necessary, but our findings in this pilot study provide a strong basis to suspect that MRE technology can identify changes in muscle tone and stiffness that could previously only be identified by physical examination by a physician or a therapist," says Jeffrey Basford, M.D., Ph.D., a Mayo Clinic specialist in physical medicine and rehabilitation and an author of the study. "Prior to these findings, we did not have a good diagnostic test for myofascial pain syndrome."

An MRE employs standard MRI equipment with a few modifications, and works by measuring the wavelength of vibrations sent through the tissues. A vibrating metal plate is placed on the patient causing muscles to contract and stiffen. When this occurs, researchers can measure the elasticity of muscles and detect abnormal hardening of tissues, which in myofasical pain syndrome can cause pain. "
