Yes, I agree that the most likely cause, but certainly not definitive, is a compressed nerve from a bulging disk, rotated/tipped vertebrae, or sides from the gear. It is not uncommon to experience back and neck pain during a cycle, especially if one is not doing the other 100 things to augment the effectiveness of the gear while minimizing the sides. For nerve pain, one must take seriously, as it could be something more serious. For initial relief, use ice NOT heat, as that can further the inflammatory process. Cold compress for 15/20 minutes on/off. Stretch and have your back massaged and/or pinpoint tight knots with a handheld massager. Be cautious on your lifts (as stated) and don't further aggravate it by lifting harder and ignoring it. That's when something minor can turn serious. If no relief, consult with your physician and/or chiropractor (if you can find a highly reputable one, he/she can really make a difference). Best of luck!
