I have cervical lymph node swelling just on the left side, I have begun snoring incredibly loud at night- so loud that I wake myself as well as my spouse, and I have a constant ache in my left upper arm and left shoulder. I went to my PCP today, and she ordered TSH level and a CT of the neck and chest. Anything else I ought to ask my MD to check? I am 40 yrs old with a negative health hx, no tobacco hx, and min. ETOH use. Since my time for taking care of myself is limited due to other commitments, I just want to make sure that I can be as efficient as possible when I do go see my MD.
