Sorry to hear of the difficulties with the spinal fluid. EEK! Glad to hear it's not the implants (hope the cause is found). I remember having so much tweaking for my cervical; more so than my lumbar. I finally figured my problem with the cervical was the stimulation at the back of my head was just too unpleasant. I was thrilled, upon telling this to the rep,to learn that there were separate leads that went down my arms than the ones that went to the back of my head. She 'disconnected' the leads from the back of my head off my programs. and with that, chose totally different programs altogether.
Hang in there.... hopefully they will get your cervical recipe just right for you soon.
Thanks for dropping in with an update!!!
