@I too have bee battleing this exact issue to the point where after 45 yrs I had to go on disability.My pain started as yours from hrs of sitting in my truck to the point where I can walk across my living room but thats it.I had done injections but did nt really help.Heres the best part of the sciatica is that it has aggrivated my nerves to the point i now live with dabilitating poly neuropathy.Tried all of big pharmas soothing fixes,but no more releif than than a really bad sleep.This has now become a very big issue that if you sit in a hard chair for an evening meal,you will get the worst zing in your butt cheeks and to stand would be impossiblebar0961
