the cracking sound from joints is NOT caused by the bones popping out. It is caused by nitrogen bubbles being released.
Wiki it.
As for your problem at hand, I believe it is probably that you have just overestimated your flexibility with your hands. Be careful as RSI may occur as a result of trying to overdo things.
Remember that RSI does not only create pain at the wrist joints.

I never had any problems with stiffness of fingers during starcraft. But my speed at starcraft is horrible and i've played piano for a long time. Regarding playing piano, maybe somewhat similar to playing starcraft, i always played more fluently if my hands were warm and if i had done some easy excercises before seriously playing. Maybe playing something like osu just before playing starcraft will help a bit, in the sense that you force your fingers to be active before you actually play starcraft. There are of course numerous ways to achieve being warmed up.
I wrote this all under the assumption that this is not a medical condition. If it is, just see a doctor. Also, i wouldn't know anything about the shaking. the only time i had something like it was when i faced some serious stress over semi-long term.

instead of focusing on how fast to move your fingers, focus on what's the next step in your game.
your fingers will follow.

At some point every time I would crack my fingers my whole hand would proceed to go numb. Doesn't happen anymore but still

However i dont feel any pain anywhere.

Playing an instrument really helps, I've never had problems with finger dexterity in SC2, my brain if anything cannot keep up with my hands.

Cracking joins has no bad effects according to long term studies over the years. It just releases some gas and gives temporary relief and make it more flexible for a few minutes. But the more you do it the more gas it will be required to the joints because of losing it so your joins will try to adapt to it by enlarging the connection are to keep more inside. The feel of stiffness could cause from that but it shouldn't have any serious effects like you say. I believe it's caused by something else or you forced your fingers to the point you must not. Seeing a doctor would be good for you.

Cracking your fingers regularly,is very unhealthy btw.

Could any of you show us actual proof that cracking your fingers is bad ? I read somewhere that it's just a myth, but unfortunately I don't remeber where I read it.
|
Yes, you have to start doing exercises. Yoga is extremely helpful when it comes to making things more flexible. Cracking your fingers is a really bad idea (bone against bone at an extreme angle for the joint, eventually it will be painful and wear your hands down!). I googled "yoga exercise for fingers" and got multiple hits from youtube. I would def. give that a shot for a couple of weeks, and see if that helps.

I try not to crack my fingers to often, but I do continually do it (through life, that is, so not every day but sometimes multiple times a day). Studies continually tried to link arthritis and cracking joints, but I believe Derrida is right in that it's never actually been proven. I have heard studies that it can weaken your joint strength in the long term, so if you stop now, you should be fine, but the more often you do it and the longer you leave it before stopping in life, the more you'll supposedly have weakened your grip strength. Perhaps if you do it enough, you won't be able to pick up a pencil to write when you are 80 years old. It might take some work, ignore the pain, keep working at it, you might set a record! (AKA I'm not serious, so please do not). I think the people who suffer the most actual pains from it are the type who would do it very frequently when they crack them and crack multiple parts of each finger rather than just the simple knuckle-crack method or other obvious ways and in addition, some people really force the joints even if it starts to hurt them, rather than only cracking if it feels 'natural' and pain-free to do so (I've pretty much stuck to this when in the habit). Use the clenching+unclenching (correct term?) and other exercises and definitely rebind keys to suit you, make sure you are comfortable with the keys. Should people avoid black switch mechanical keyboards? I find my rubber dome keyboard comfortable though but I thought blacks were specifically weighted and so they always sounded heavier than rubber to me, but I thought I'd read that all mechanical switches were still lighter than rubber domes. Hmm...I'm off to that thread again now.

It sounds like tendonitis. Don't flex your wrist/fingers or crack your knuckles. It's very easy to overextend when you're doing those wrist exercises, (bending your wrist backwards or forwards). If you do those stretches, go very slow and don't exert it far; you aren't supposed to feel it stretching like you do when stretching muscles (i.e, touching toes).
What temperature is the room you're in? Cold hands will make your hands stiff. Adrenaline can make your hands cold.
But if it is tendonitis, you shouldn't be stretching whatsoever, and heat will actually just increase the swelling (don't use hand warmers if you think it's tendonitis). Ice pack on affected area + naproxen + complete rest is how you treat tendonitis.
Posture is important. Post your setup (keyboard, mouse, chair/desk height, hands in playing position). Show a video of you playing sc2 if you can (particularly want to see how you hit shift and ctrl keys and overall posture.)

Here's something: Helped me out a whole lot, though it still takes quite a bit of concentration to make a clean line quickly.

To add a little bit of substance: If you've drunk anything with caffeine in it, don't be surprised that everything shakes a little bit.
Also, do that finger exercise a dozen times or so before each game. Helps a lot. Or atleast it has helped me a lot.

Hi,
professional safety engineer here. I work in an big companies and ergonomics as well as healthcare are part of my everyday work as i care for like 1500 peopleFinger cracking wears of your inside knuckle bones as well as the cartilages. If done over years you form a cavitation which is automatically filled with water. This is what u feel. The aftermath is stiffness and vulnerability for sickneses (omg my english is bad sorry for that guys) like articular gout and rheumatism.
The shaking comes maybe from:
1. your fingers being too cold (do you fell like u have cold fingers after playing a long match?) 2. you hindering your own blood flow as u maybe have the edge of your table cutting into your arm? 3. ladder pressure (not kidding) sometimes i n have that too 
When playing sc2 I always have a hot water bag around so when a match is over i can warm up my hands which is also good to get your fingers more flexible. I can also recommend training your hands with devices like:
Black Diamond Forearm Trainer (cheap and trains your hand and finger muscles in the long run)
or
Harley Benton Fingertrainer (for guitar players helps wonders as well)
Thers lots of devices but i made good experiences with my employees here 
God i didnt think i could use my job knowledge on TL Thtas kinda funny
If you need more information on desktop ergonomics or stuff like that just ask !
Greetings from OSnabrück.Germany

Best advice ever, and from a professional.
Say thank you, OP <3

And I am also very inflexible  So these things are not automatically bad. But then again, I have gotten faster just from practice. Slowing down sounds bad... Still not sure this warrants a thread tho.... EDIT: fell for it gosh darn it. I'm too tired to see through it. i have the same that i can't hold my hand sitll but my hands but i my fingers are quite flexable and fast (can hit easily around 500 apm in bw)
