I'm 4 months post op from l5s1 fusion and am still so tired. Went back to work for 6 weeks and couldn't handle the workload, stress, or sitting so i had no choice but to resign in order to focus on my health. I can return when I'm better but now I'm wondering when that would be. I'm 52 and otherwise in good health. I've never experienced such low energy in my life. Anyone else feel the same or have any input?
