I have been suffering severe back pain for around 15 yrs now, I am currently on Amitriptyline and tramadol as needed, I have also had physio, pilates and several cortisone injections in my lumber , I had an MRI scan recently and was told i have osteoarthritis (facet joint disease~) and a bulging disc? I get terrible nerve pain at night down both sides of my thighs right down my legs so cant lay on either side at all, but to lay on my back isnt comfortable either! Any other advice please?
