I did mine last friday and like you have been in agony,getting out of bed on a mornning is an absolute nightmare, im taking pain killers to no provail and putting heated bean bags on my back which helps with releaf for a short period of time but not cure, im trying to keep moving as sitting too long makes it worse, you just stiffen up if i come across a cure il let you know but dont hold your brearth. i hope you get rid of yours.
