Really hard to tell.
My wife had a pain like that in her neck once in 1991. She went to the chiropractor I was seeing, he helped her with two adjustments, that was it.
Try taking care of it first. Get a massage, take a warm bath, take alieve or ibuprophen, sip tea, sleep, stretch the muscles very gently while warm. Destress, decompress, heal.
Acute "back" problems - or neck, etc. - are about 95%+ of the time muscle only. They will heal by themselves or through physical therapy, massage, acupuncture within 3 months.
We are the exceptions here.
We are the chronic folks - long term, as opposed to the acute - where the normal advice on back pain does not apply. You may find more generic advice through articles at *****, etc.
Good luck! Go to the ER or doc if you have a lot of numbness, dizziness, pain is so intense you can't stand it, etc. In the meantime, be very nice to yourself and tell the world to go away for a while.
