PSA for the board regarding potential pain management

Backstory: I hurt my lower back on Wednesday doing dead lifts. I don't know how, I was doing my second rep and something happened to my back on my lower right side.

I've been in a decent amount of pain and discomfort for the last 6 days which has kept me out of the gym. I've taken aspirin, rubbed on Icy Hot balm and neither did anything.

I mentioned this to my dad, aged 66, and he suggested I try Voltaren Gel. It's a non-prescription arthritis topical treatment.

I put a quarter size dab on my affected area about 6 hours ago and the pain is completely gone. I can't believe it. It is crazy how seemingly effective this stuff is.

Has anyone else ever taken this for pain and had similar results?
