Meloxicam
"I was prescribed Cymbalta for fibromalgia and it was ineffective and expensive.  A friend told me about Meloxicam and now I'm virtually pain free.  I only take it 3 days a week the night before I go on a morning run.  It started working within 2 days.  Recently I didn't renew my prescription and the medicine's effect took about a month to wear off. "
