I do notice sternacleidomastoid (scm) being tender/
sore, and up
under jaw, behind
ear, in
ear, in rt lymph node area especially behind it, but lymph node not swollen, but just in that area. I know the scm attaches in tha region, and there are a host of neck muscles, and even under chin in diagastric muscles, plus shoulder &n neck muscles that can come into play here. My trapezius muscles are often sore (after chores, dishes, walking dog,etc) as well.
