Hi Michelle.
I had something similar. For me it turned out to be a referred pain pattern from my neck where i had a ruptured disc.
Were any of the scans of your neck? Although a referred pain does not cause a physical knot. Hmm...
Something is a treatment called dry needling. This is much different than accupuncture.
A trained physical therapist inserts an accupuncture size needle into the affected muscle, sometimes directly into the knot.
