Hey .. No they lasted about 2 wks for me then nothing. I just had the ALIF surgery where 3 disc were replaced and spacers were put in 4 and 5 and 6 /SI.. I had torn muscles, nerve damage,lgaments torn... I had my surgery 4 wks ago and I am still in massive pain from the nerve endings n ligaments. I was cut thru my belly to have this done which has not bothered me once, but the back is terrible. I had the epidurals,nerve blocks and both hip SI injections every 6 wks since July 2010 and it just wasnt working and my disc had collapsed so surgery was my only option then.. hope you are doing ok and feel free to talk anytime ..thanks.,<Kristi
