They are usually under the skin, under my arm next to my left breast. The other symptom is my lower, front of my neck feels like its being squeezed. It's taken many years, up until just a couple years ago to find the trigger because for some reason, it takes about 24 hours before symptoms arise, and the trigger is touching/cleaning my right ear. My doctor thinks its GAD, and has had me take anti depressants, which causes other issues. When I lie on my left side, you can feel it pretty strong, so I cannot lie in bed for long. Thyroid tests come out normal.
