Dear PhilXD,

I would recommend you went to a physiotherapist who could run all the necessary tests on you to figure out if your pain is somatic referred or radicular and to what extend neurodynamics are involved. Obviously you can not perform these on your own or instruct others to perform them.

Your case sounds like it could be a series of things and at least for me, with my experience, it's hard to tell without more details (ie slr, what stretches you were doing, sensation/strength/reflex, condition of C/S and many more)

I know this doesn't help much but it's better than nothing Good luck and let us know how it goes
