Natures tears of the symptoms means a more systemic disorder should be cosidered. There is no specific disorder which this suggests. Disorders which should be excluded include inflammatory conditions, connective tissue disorders, B12 deficiency, and thyroid dysfunction. A neurologist should be able to evaluate this problem for you with some blood work, and perhaps a EMG (MUSLCE/NERVE TEST). Good luck.
FYI - I'm 33, female & all tests (blood, emg, nerve conduction, etc) have been normal. I've been told everything from it's anxiety to possible B12 def. to hyperthyroidism to simply a neurological syndrome that may never be diagnosed. Nothing has ever really tested out...which is good, but still keeps me searching for answers and relief. Best of luck.
I also just started having numbing in my nerves in legs and arms and lower back. I know that I have derignated discs.
