The 1.5 cm mass in the posterior part of your neck, under your earlobe may or may not be related to your achy neck. If it is an inflamed lymph node from an infection, such as a systemic virus, or local bacterial skin infection
, it will be tender to touch, and may cause the local muscles to be tight and sore, but not always. If the enlarged mass is a lymph node that contains another disease, such as cancer
, it would typically be very firm and not always tender either. A physician can distinguish between these conditions and make an accurate diagnosis. An osteopathic physician can also manipulate your neck muscles if that is needed as well as tell you whether the mass is a lymph node, or a different type of mass, and whether further workup is necessary. The lymph nodes on the left side of your collar bone that come and go should also be evaluated. I have seen some diseases that cause lymph node enlargements sporadically, and those should also be evaluated by a physician. An internal organ problem in the chest or abdomen can cause the left sided lymph nodes above the collar bone to become enlarged. It would be important for your physician to evaluate your heart
, lungs, stomach, and liver and spleen for enlargement or tenderness. Blood tests and x-rays may be indicated. If you have fevers or chills, weight loss, or other symptoms, seeing your physician sooner than later is recommended.
