I didn't notice how old the post was for lumbar block. I'm afraid....I have had to date 9 total starting with my lower back 2 blocks for my right foot and 2 blocks in my mid back then 2 blocks in the back of my neck and 2 in my front under my collar bone for the pain in my right ARM. They aren't bad they will put u to sleep and for me they helped oh a total of maybe 3 days at the most. The last one Monday a week ago for some reason upset and caused my foot to swell which hasn't gone down yet and my entire ARM has had no relief whatsoever. I made an appt to go see my pain specialist and he has decided to change me from 3600 mg of gabapentin per day to trying lyrica. This is what I'm scared about.
