Not to scare you, but I advise following up with a doctor as soon as possible. My 21 year old brother who was otherwise completely healthy suffered a similar short pattern of pain due to blood clots (not related to vaccine) but with severe neck pain for a short time one night. It went away after that night, he was fine for 3 weeks with no pain or issues, was working out fine, etc. and thought nothing of it. Suddenly one night went from perfectly fine sleeping to suffering a major stroke due to a blood clot in his brain within a 10 minute period, unable to do anything himself to get help as he lost all motor skills. He said in retrospect he wishes he had followed up with a doctor on the thing he thought was no longer an issue 3 weeks before. There are genetic tests they can run, as well, such as to see if you might have factor V Leiden.
