Continued observation of the lymph nodes should be done. Any infection or inflammation can lead to enlargement of the lymph nodes. If this is the case, appropriate antibiotic therapy can be done.
If the lymph nodes continue to be enlarged or are more prominent, a referral to an ENT can be considered for possible biopsy.
I would also consider a blood test to evaluate the blood count - possible lymphomas can present this way.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.

Forgot to mention that the PCP ordered a CBC (came back "normal" but I didn't get the #'s) and a B12 test (came back borderline low at 270). Since I've had problems in the past keeping my B12 level up he prescribed monthly injections, which I've just started.
I woke up Saturday morning and got in the shower, I noticed a lump on the back of my neck while washing my hair. The lump had a appeared over night, and is tender to the touch. I am having a hard time distinguishing between it being a knot in my muscles or it being a swollen lymph node. My neck on the right side is very tight and sore. How do I tell the difference and should I go to the doctor??
