I have had two back surgery s one for a bulging disk which was thought to cut off nerve functiion to my legs and then a fusion on my L4 and L5 disks as all indications were then my disks were compressing the nerves to my legs. Now I have fluid retention in both legs, fluid on both knees, stiffness from my waist down, legs swollen to the point of inmobility and toe nails popping off my big toes. I have trouble standig, my knees give out and I fall, I have trouble getting in and out of vehicles and standing from a sitting position. I am 55 years old.
