Thanks for your responses. Neck is much better today. Not experiencing any increased anxiety over the new medicine. Thank you
Are you having an increase in anxiety over taking a new medication dose? Anxiety and tense muscles could be the culprit.

I looked it up and a stiff neck is not listed. You slept wrong
