My levator muscles and a little bit of my rhomboids just gave me an awful flare up.

The muscles aren't spasming. They feel like they're *alive* and swollen tender and needly. Then it spreads to.my scalenes and ribs creep up

What is this! Could this be caused from just a small part of my BP being compressed or is it inflammed?? The muscles or the nerves irritating the muscles. I have tight pecs but they don't light up like this

Any advice appreciated tia. I want to.go to a docvwith some specific ideas of how to treat this as I don't trust doctors.
