muscle spasm
"Had a very nasty Lumbar disc prolapse which was causing pressure on my Sciatic nerve, I was prescribed 2mg Diazepam and Codeine (which I haven't taken). 
Ordered to take the Diazepam 3x daily but I've always been sceptical about taking medication, however certain mornings/evenings became unbareable therefore I bit the bullet and took the Diazepam.
To my surprise within 20 minutes symptoms reduced, hopefully returning to my beloved sport within 4 weeks now!
I must add I have been undertaking mobility exercises and stretches which I believe is reducing symptoms as I'm feeling the need to take less medication and I'm gaining more range on my stretches now."
