When you’re on your daily run, which you’ve been doing for years now, and your big toe on your right foot starts hurting like crazy. You figure maybe you stepped poorly and it will just be sore for a few hours. Then those few hours turn into days. Then you think maybe you sprain something or even tore a ligament, so you get with your doc for a consult.
After testing, a sprain, tear, break, and even gout are all ruled out.
Dude you have arthritis in your right, big toe. Here, rub some Voltaren(tm) gel on it and good luck. Nothing else can be done.
