Ok so 30 minutes ago I had this HUGE painful spasm in my back, took me 10 min to get out of bed, tried to walk around one slow step at a time to try and ease it. Oliver was waking so spend a few minutes trying to dress, then picked him up while still in extreme pain and walked slowly to my feeding chair as it's the highest chair I have. It is still painful and I have no idea what to do. How long do these take to ease. All the ones I've had before only lasted a few minutes. 10 at the most
