muscle spasm
"I had a back problem that lasted over 10 days. I went to chiropractor and tried everything. I took one dose of Skelaxin - pain was gone in less then an hour.

 

I have tried a lot of "muscle relaxants" over the years.  All they do is sedate you.  This one worked and it doesn't mess with your head -- I noticed no sedating effect, even after a glass of wine.  I personally do not like to feel "drugged." I hate feeling the effects of opiates, for example. This had no side effects (my experience, yours may be different).  Main feature was that the terrible pain was gone."
