Breast Reduction w/ existing Cervical Spine Disease

I have quite a few of the symptoms of health problems due to large breasts (paresthesias (incl. pinkies as of 4/11), neck, back pain (esp thoracic), chronic migraines). However, I have also had an MRI that shows degenerative changes with 3 level disc disease in my lower neck. I have not had treatment on my neck, but am considering phys. therapy. I do not want to do spinal surgery because of the risk that it may not resolve the symptoms and potentially stressing more of my neck leading to future neck surgery. I am also considering a breast reduction.At least if the symptoms remain I will at least be rid of the heavy sensation on my chest, be able to buy bras that actually fit at any store, and not have to rearrange my chest to rest more comfortably!  Will this likely be denied by insurance automatically d/t spinal issues? I am 29 y.o. w/ 32F bra size, professionally fitted. Who do I discuss this with? Primary doc, chiro, PT, cosmetic surgeon?
