hairdresser,
I get trigger point injections into these area. The one on the rhemboid they cannot get too low to as it can hit the lung. But about 5-6 spots.

But, it was realted by my neurolgist and several TOS doctors as where the nerve inserts into the muscle. The nerve is inflamed and the muscle makes a splint to protect it.
With trigger points, the doctors uses a marcaine and a novacaine type medication into the triggers. My medications are topomax, for the nerve pain, and valium 5 mg to 10 mg in a flare as needed for spasms.
Toradol for flares.

As a previous haridress in my former life I know the spot you mean. When you lift your arms , under the wings and coming around the front to the armpits.

Do you also get the one from the wing up into the base of the skull like a knot in the base of the skull?
That one triggers my cervogenic headaches.
I find keeping a pain diary and taking it to the doctors, every one, keeps my spymotms and complaints identified to them.
Hope you find relief.
Di

Folding clothes, hanging up decorations, rolling out dough are flaring me.
