I have 3 enlarged nodes under my jaw, 1 on the left and 2 on the right. I worry about them a lot. I have had 3 gp's check them and they all said that they are fine, moveable, squishy etc. And every time I go to my own gp, I get her to feel them again and she tells me the same each time. Blood tests were fine. I have other symptoms such as pinpoint abdominal pain and bubbling, wrist pain, knee pain, numbers and tingling in my extremities, facial numbness, mouth sores... Amongst others. I have another abdominal and pelvic ultrasound soon.
Like the other posters, my gp said nodes can swell and never go back down. She said she would know a cancerous node instantly because of how they feel, rock hard and immoveable.
