10.

I have developed a sharp burning pain in my left wrist. According to my mother, it's being caused by a reformation of the ganglion cyst that likes to appear and disappear from the back of my left hand. She says that the same fluids that filled the cyst have now made their way into my wrist joint, and that I will need invasive surgery followed by physical therapy.

The causes of the ganglion cyst, as well as my moderate cases of carpal/cubital tunnel syndrome(s), include, but are not limited to, the following:
1. Excessive typing.
2. Excessive and/or improper playing of the guitar.
3. Excessive playing of the piano.

The moral of the story:
I should start smoking.
