I had a medication added and forgot to ask my doctor a very important question. Can anyone tell me how long you have to take it for relief and what I should/could expect? My doctor pounded out my joint pain and now took on my back. I'm on 75mg x 2 and as excited as a child on his 1st day @ school. L/4-S1 problems extreme pain and numbness thighs and feet and right calve. Pretty expensive stuff but if it works hallelujah! Has anyone heard when/if they're coming out with a generic? I'm all giddy and that's good!
