muscle spasm
"I have had chronic pain for 12 years, have regular steriod injections in my spine and botox in the large spinal muscles.  I take pregablin 3 times a day and baclofen at night.  I used to use diazepam quite regularly for muscle spams before getting these drugs, recently missed a few pregablin and needed my diazepam.  You still feel the pain of the spasm, but the drug makes you less tense, so you don't excerbate the problem.  It enables me to start moving around gently and get back to normal quicker."
