Diclofenac
"Having been diagnosed with degenerative lumbar vertebrae-- this medicine is AWESOME. It works very well. I've used it on my sore feet (lucky me with bunions! Too many years in high heels) and it works very well.  Also, I work at a computer and drive for work a lot, it really works miracles on tight/sore shoulder and neck areas, as another poster has mentioned.. you do feel more "loose" after you use it.

Finally, it smells pretty decent.  I was concerned that I'd walk around smelling like Great Auntie Momo...  It just has a light, semi fresh smelling scent--not medicinal."
