Are you describing your jaw line under the ear?

If so, there are salivary glands located there and they can swell up if you get dehydrated, etc. They feel soft and squishy when full. My doctor recommends sucking sour candy twice a day.. like lemon drops or Jolly Ranchers. This stimulates the glands to empty and the swelling will go down. If you don't do this you may over time develop stones in the glands...this requires surgery and can be very painful, and never really resolve like they were in the first place.

There are also lymph nodes in that region, so they may be contributing.

it's my submandibular gland i think.......but also when i press up under that same area, on the underside up into my jaw it feels fat and hurts. i will try sour candy. that is interesting.

i am thirsty all the time but a uti test came back negative. hrmm.

i really think now this from the mag deficiency and a build up of lactic acid in my jaw.
