I had crushed the top joint of my middle finger very badly under a heavy iron plate. I thought that my finger would be mush if I pulled it forward under the plate. When I had then freed it, it swelled like a balloon within seconds and at first I just ran into the house and put healing master and ice on it. Every few minutes I put healing master on it again. In the following days I then put healing master on it 3 x a day. Naturally, my finger was blue and in between I was also afraid that the bone was broken. But I didn't have to go to the doctor. My nail didn't have to be opened up by drilling, nor did it have to be pulled.
