muscle spasm
"Preexisting spinal stenosis and diabetic neuropathy, then twisted back getting off a MRI table. Searing pain and unable to walk at all (normal is with a walker).  Fell the next day and ended up in ER, 2.5 of valium and was able to self-transfer from bed to wheelchair to toilet etc. 
Dr took me off valium and put on tramadol and it does NOT work as well, am losing mobility now.  Saving the remaining valium for very bad days while waiting to see a pain specialist. 

76 yo, many physical issues, why can't they just treat based on quality of life at this point?  With the tiny dose of valium (2.5 ,3x day) I can move.  without it, I'm in agony."
