I've had this problem for several months. Tried resting it, but it doesn't seem to help, it still hurt when I kick and hit the bump.
I'm pretty sure it's cartilage.
I've been massaging/rubbing it every day for a week. Haven't noticed any change.
Someone told me to try to warm up the cartilage and then rub it out. And now you say use cold.. I'm getting confused
What effect does thai oil have? Is it anything like tiger balm? I've started using that now...
