I am a 34 year old male. Had Alif on 10/20/2015 on L5S1. I am just starting weak 4 and have a lot of low back pain especially when I am in bed and try to roll to a different position. The pain fells like it comes from below the disc in the upper butt cheeks tailbone area. Has anyone had this before? Also just the whole low back area in general. Will it go away? I also walk a mile to 2 miles a day. Am I doing to much? I'm not seeing any progress in the low back pain going away and am getting depressed and frustrated. Please help! Thanks!
