A small lymph
node swelling in the neck area might be suggestive of a minor infection in the neck area. This can also cause tenseness in the neck muscles.
You need a focalized examination by your physician to look for any possible infections. FNAC of the lymph node will be helpful in detecting the pathology.
I hope this information has been both informative and helpful for you.
