Sometimes, people have life problems that can be entirely solved by doing one thing. (doing X made my life 0.1% better, PERMANENTLY!) These are not things like "This TAP made me exercise more frequently", but rather like "moving my scale into my doorway made me weigh myself more, causing me to exercise more frequently" - a one-shot solution that makes a reasonable amount of progress in solving a problem.
I've found that I've had a couple of life problems that I couldn't solve because I didn't know what the solution was, not because it was hard to solve - once I thought of the solution, implementation was not that difficult. I'm looking to collect various one-shot solutions to problems to expand my solution space, as well as potentially find solutions to problems that I didn't realize I had.
Please only put one problem-solution pair per answer.
I had bad carpal tunnel pain and RSI due to my coding job 3 years ago, to the point where it was very painful to type, and moderately painful all the time. I was worried I would have to find a new career.
I solved it by seeing David Bacome at Psoas in SF. After about 7 sessions the pain went away completely. He also taught me how to do some exercises to help prevent it from happening again, which I do whenever I start feeling lots of tension in my wrists. It hasn't been an issue since then, and I have no problem using a keyboard for both work and many of my hobbies.
Basically, you move your arm around until you get to a position where it starts to hurt (or hurts more). Then you try to find a spot with your other hand where if you apply a shear force, the pain goes away when you try to move again.
