What is your pdoc going to do about the spurs? nothing? Are they having you do cervical extension exercises at PT? You need to get that disc material "sucked back in" with cervical extension. The nerve compression/neural tension will get better when the disc material gets back in line. Hows your deltoid, bicep and wrist ext pain/strength at this point. The main important thing and they should have told you this at therapy is pain free exercise, pain free range of motion. As your disc bulge improves so will you referred pain. Since you didn't suffer any structural damage to your arm, I think you could leave it up to your own discretion, you don't have any restrictions, Id go maybe 2-3 sets of 15 dumbbell curls for a couple of weeks, ease into it. Remember pain free ROM, pain free exercise.
