However, it's not enough. It's starting to effect my ability to play guitar pain free. Are there products that you can wear on your fingers that add some padding? I have thought of buying finger picks to use almost like fake nails so my finger tips aren't hitting the keys at all. For those of you that have experienced this, what have you done that has helped?
I'm not a doctor but there are a number of medical conditions that can present symptoms like this. Could be something as common as carpal tunnel but it could also be lack of blood flow, infections, arthritis setting in or other odd things. I would definitely speak to a doctor if you haven't and even if you have maybe a few different doctors.
Maybe you could come up with a solution for guitar playing as well. I think it will require a reasonably capable EEG device (lab-grade better) and playing different chords of the guitar. You may need an EEG headset that is electromechanically stabilized and use some algo to filter out muscle movement (not that easy, but also not that hard).
For an immediate solution: skin-fitting cotton gloves with some kind of lubricant?
