Quick pain relief for bruised foot

I have been de-cluttering my house and I dropped a very heavy item on my right foot. There was instant swelling, bad bruising and pain on the top of the right foot. I figured that the injury called for the big guns, so I took one of the super biomagnets from my Wellness Kit, taped it under the foot, beneath the bruised area, negative side towards the foot.

The foot was pretty sore for a couple of hours. And also uncomfortable as I had to walk on my heel because of the size of the magnet. So after a couple of hours I took it off. I am 59, and from past experience, I would have expected the swelling and pain to last for at least a week, and the discoloration to last for several weeks. However, by next morning, the swelling was down, the pain was gone, and the discoloration was almost invisible.

Thank you super biomagnet. CG
