Neck/back pain?

Not sure if this is a thing but it’s now the second time it’s happened in ~3 weeks so figured I would ask.

After my long run ~3 weeks ago, I got an insanely stiff neck that lasted for like 3 or so days, didn’t have most of my range of motion looking to the right. Mostly just took Tylenol and put heat on it. It’s happening again now except deeper into my back instead of my neck. Did a pretty intense strength and conditioning class yesterday, so maybe it’s tied to that?

Is this totally just a me thing or is this something you see with runners as they increase mileage and balance strength training in a training block? If the latter, any recommendations?

Not only is it painful but it’s also just a nuisance!

Cheers,
