I had a benign tumour on my spinal chord removed in September. Before removal I couldn’t sleep due to sciatic pain, and legs were getting weaker to the point where walking was becoming difficult. The operation to remove it took five hours. It has now been 8 weeks and everything has bounced back to normal. Give yourself time Rod and things will undoubtedly improve as the site heals and residual swelling dissipates. Best of luck!
