you got them, i will give you some good news

mixed with a little bad[&o], i have had done what you are going in for, i have/had a herniated disk and severe hip and leg problems, nosleep, no rest and could not get comfortable, the best thing i could do was walk, sounds crazy but i got more relief walking than any other activity

...
back to the injections, the first one i recieved worked like a miracle drug, for 3-4 months i was viturally pain free, the second injection missed the mark and i never recieved any relief[:@][&o], the third injection lasted a good 3 months also, the forth time lasted about a month or so with a fair amount of relief... at that point the doctor ( who was great, even wore camo scrubs

) performing the procedure told me "look we can keep doing this from now on, but you really should address having the problem fixed"
got another doctor that performed that procedure and i am 80% recovered, meaning i have a lot more good days than bad, but there are some where my hip and leg will ache for some time, and i have also found that a lot of your recovery and limitations are controlled by your thought process upstairs, i refuse to give up/in its just my mindset...
keep a positive attitude, heed the advice and exercise the doctors advise, and keep praying

and i will too
