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 is not swollen, but just in that area there is pain. 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. Often, like today, the area under my chin is tender.
