I have "maybe" a swollen lympnode in my neck can this be caused by sleeping wrong on my neck? its located by my throat. i have no fever or illness.

Unlikely: If it causing u a problem see your PCP for evaluation.

No : A lump in your neck is a very good reason to go see a doctor. Soon. Lymph glands in adults require immediate attention.

Lymph node: Lymph node are a reaction to an infection or inflammation, such as a cold or skin infection or tooth problem, and the ones in the neck are pretty common and should resolve on their own within a few days. If it persists, see your doctor.

Likely from dental: Not unique to develop a swollen node secondary to dental issues such as gingivitis or an occult tooth abscess. This is minor, but could be a sign of an emerging bigger problem. Might see your dentist first, as unlikely this is due to strep throat, sinus infection etc.
