spinal fusion

I have had 2 spinal fusions now, one and the caqe moved so it was redone. i know have swelling in my left leg and numbness. upon my second surgery the spinal sack was ripped and a nerve was stripped I have been off of work for a year in august. I had a surgery in December and in March.  I still shake all the time and my legs tremor alot. I can not lay on my left side, I have only been up and about about three weeks, i  am not to see my spinal sur. until 4 more weeks but i am concerned about my left side. i have had trouble since 2004 and had multiple nerve blocks for three years, and then nuerologist who said nothing is wrong with me, then the spinal dr. saw L4 and L5 buldging.
