Honestly, Cheryl, with as many clean (for ALS) EMGs as you've had, plus clean for ALS clinical exams, you may be standing in the way of yourself by continuing to focus on a disease you do not have, as opposed to continuing to look for solutions to what you may have. This forum can induce anxiety, and actually harm instead of help, those who are already in an anxious state of mind. This is a 7 page thread with not one page showing signs of ALS.
I'm not sure what you have, to be honest, but I do know what you do not have, and that's ALS. You've been cleared and that's a wonderful thing. It's time to look to the future and go forward with solutions to your right hand issues, whatever they may be.
Best of luck to you.
