I wrenched my back pretty bad a couple of years ago, ever since i cannot do any activity without worry that i may throw my back out. If i wake up in the middle of the night to go to the bathroom just the slight tilt i have to go through leaning forward to lift up the toilet seat can put me out of comission for two to three days if i dont bend my knees to lift the seat. If i have to mow my lawn (riding lawnmower) just the bouncing from that only allows me to mow for 15 mins or so before the pain in my back is to bad to continue. Ive reached out to my doctor for this and he has had me take a bone scan (Nuclear medicine used)which he said showed nothing abnormal, he then sent me for a M.R.I. which also showed nothing abnormal. I am at my wits end with this, if you were to wear a belt with your pants then the place where the belt would pass over your spine is where the pain is located for me (Feels like it would either be the last or the second to last disc in my back). the pain can be so bad that it buckles my legs. if anyone has any information that can help me i would appreciate it.
