question: I have a compression fracture C3 and a crush fracture C4/C5. the pain in my neck is unbearable. I find if I look up to say hand a light to my husband, next thing I know I am on the floor, dry retching. I have no recollection of hitting the floor Is it best to put replacement disks in C3/4 and C4/C5 or fuse my neck and have little or no free movement in my neck? PSHx disc replacement L4/5 and L5/S1, I was part of the trial of the procedure 14 years ago. I am Leidan Factor 5. Have had 6 DVT,s and X2 PEs. I also suffer from pheripheral neuropathy of both lower limbs, up to 5 cms past my knee caps. Currently I am taking arava [chemo drug] for auto immune arthritis and IVIG for Tx of neuropathy. The immunologist I am under does not know if it will work. Based on this I see myself as a Lab rat. Any thoughts???
