Tom's right- you need to see a doc to get this checked out- you need a good differential diagnosis to rule out either neck or carpal tunnel issues. I have cervical spondylosis with osteophytes- a hazard of weightlifting, I'm afraid. I was able to control the pain and numbness with isometric neck exercises- I still lift, though not as heavy as I used to, and I still have occasional discomfort, but it's manageable.
I hope this doesn't offend, but I really should mention this. Do not, under any circumstances, let your chiro manipulate your neck. If you have compression or spondylo, manipulation can make it worse- much, much worse. I don't mean to criticize chiros- even though I'm a member of the "traditional" medical establishment (epidemiologist and ex-athletic trainer in a previous life), I think they have their place, but this is one place where chiros can do more harm than good. See a good orthopod, decline any surgery (you don't want that either!), get X-Rays (not an MRI, unless they do it sitting up, which is pretty hard to find- you need a sitting c-spine film to find the compression between the vertebrae), and ask for a referral to a physical therapist who's experienced in sports medicine. You want this because you're a cyclist, and cycling can really make your condition worse. You need exercises to condition your neck and auxiliary musculature so you can ride into your sunset years.
This is a potentially dangerous, but manageable condition. Good luck and take care.
