One doctor has given me a quote for a fusion for scoliosis at a cost of $35,000 that includes a rod and screws up to T9. I have extreme pain in my lumber and pain down my leg I cannot walk further that 20yards nor stand for more than 10minutes, I am 65 years old. Another doctor suggests I have fusion at L2/3,L3/4 and L4/5, with a 75% pain relief. Who should I choose considering I don t have easy access to $35,000.
