Several years ago I had a fungal infection around my fingernails on one hand. It caused my skin to become dry, cracked, and discolored. I was really busy with work at the time, so I ignored the problem for months -- and also because I'm a guy.
I could have gone to the doctor to have it treated, but I decided to try using the mind-body connection to see if I could heal it on my own. For three days I meditated for 10-20 minutes, imagining my body healing and my fingers returning to normal. After the first day I didn't notice any change. On the second day it looked like there was some improvement, and by the third day the infection was completely gone and my skin was totally normal. I didn't expect that result so quickly, so I was a bit shocked at how well it worked.
