Hey Guys - This is gonna be a looooong post... I've been searching here for months hoping someone has posted about the troubles I'm having, but nobody has, so I guess I'm the first!!! I'm pretty sure this is the right forum as this has apparently come from plaing bass for 16 years! My hands (both of 'em) feel stiff and slow ALL the time. My left is definitely worse than my right, but both seem to be affected. Also, my pinky on my left hand slows down and actually stops during a trill on the bass - and the side muscle in that hand (the "karate chop" muscle" gets ROCK HARD. PLUS every so often my pinky and ring fingers on the left hand will momentarily lock in the straight position (not closed like with trigger finger) while I'm playing. I've been told : 1. It's not CTS (as it's mainly affecting the pinky and ring fingers); but, nobody has diagnosed it as cubital tunnel either. I did have the "shock" test done by a neurologist. 2. That 16 years of just picking up the bass and shredding without warming up (for my left hand) and 7 years of bad ergonomic posture while using a mouse (for my right) has given me a WICKED case of tendonitis in both forearms. 3. That the problem with my left hand is most likely in my left shoulder as I'm all knotted up in there. BUT After all of my research on tendonitis (including Randy Kertz' book), I can't compare what I have to it - I have no pain. Just slow, tired, seizing up hands. It's getting harder to tie knots and pick coins up off of the table. I have received and done the following treatments in the last 8 months: Acupuncture, theraputic massage, physiotherapy, heating pad, ice packs, daily stretching of both the forearms and the lumbricale muscles of the fingers, new workstation and keyboard tray, lowered the height of my bass (so both wrists are straight), gotten wrist braces, gotten a Comfort Strapp... I always stretch before playing. And I CAN still play... It's just that I figure the Yngwie stuff is out for me now (not that I ever tried to do it before!) If I'm stretched and warmed up a bit (and concentrating on the music I'm playing), I usually don't think about it (until I get one of those lock-ups or try to do a trill). Weird, huh? SO - has anybody EVER experienced this? Can tendonitis NOT hurt but have effects like this? I'm not looking for a medical diagnosis (so nobody tell me I have anything serious as we haven't spoken and you'd just make me paranoid! ) - I just want to see if this happens to any other bass players. Again, if you've made it this far, sorry for the long post. I'm just really frustrated!!! Thanx!!!
