How To Treat Painful Back And Limbs Caused By Spinal Disc Issues?

For about 6 years now I have had back pain. Mostly lower at first. The last 5 years I have had muscle spasms. More annoying some painful. Also in the past 5 years both calves have had constant pain. It started as just at night but gradually it s to the point where my legs feel like they are so tired. Stairs are my enemy. I get tired really easily. I get numbness in my arms, legs, hands, feet,back,and scalp. I am taking a pain killer that my neurologist prescribed, it helps but doesn t take away the pain completely. Just helps enough to be able to move around. My legs will get stiff if they are in the same position fir more then a minute. My doctor said that there are 2 discs pressing on my spine and some of the fluid around the discs wasnt there, but to basically sit around and wait for something to happen.
