If you touch something with a finger, and it feels like you get a schock? This can be caused by too much use of electronic devices, or repetation of the same movement with the fingers time after time again. To have this go away: Fill a container with water (approx. 39 Celsius), let it cool down and then put some tape around the finger, and soak the finger in the bowl of water. Within 30 minutes, the stress will be gone out of the finger! Good luck.
