Hi, I Have Lower Back Problems And One Doc Said

Hi, I have lower back problems and one doc said its spinal stenosis. My right leg mostly my foot is numb n a bit tingly 24/7 never goes away . I've been taking percocets during the day for pain, tizanadine at night to help me sleep and even naprosyn. So far I've had an epidural and recently a facet injection. The epidural didn't help and I'm hoping the facet will. Tonight it's not. I'm in pain and the numbness in my foot won't go away I kinda dread sleeping. I know doctors are trying to find other options. But tizanadine and percocets are what help. Someone said I should get a Med card for marijuana but I don't want to and employers frown on it even though it's legal in Colorado. I don't know what else can help?
