sciatica
"This drug has been a godsend for my lower back pain (sciatica.) One pill and the pain is gone. I only take it when the pain flares up, sometimes once in morning and once at night but rarely need it multiple days in a row. It also works for headaches, cramps and other pain. No side effects for me that I have noticed. So much better than muscle relaxers and opiates that make me sleepy and incoherent."
