Feels like random nerve pinches that come and go randomly on different limbs, following joint pain that also comes and goes within a few seconds. (?!)

Simple things first: Even though you are on the "older side" for growing pains, that is a possibility given the description of your symptoms. Having said that, there are other things that could be considered and looked at in the context of a full history ; physical examination especially family history. If simple over-the-counter pain meds don't help then, i recommend a visit to a good doctor.
