Some questions your health care professional may ask to determine the cause:

Your muscles cramp up after exercise if you do not stretch
If you hold yup just two fingers on one hand you can clearly see two. If you then hold up two fingers on your other hand you can now see a total of four fingers, 2 fingers on one hand plus 2 fingers on the other hand, not 396732 fingers.
Hold up your hand. Count the fingers. Hold up the other hand. Count them. Write down how many you counted. You now know the answer to your question.
With all 5 fingers, pick up something from the palm of the other hand; lift the hand, and sprinkle the fingers into the air.
Do you have a cramp ? Cramping can start especially after hard or strenuous excercise that causes you to sweat a lot, also a lack of Pottassium will cause cramping, eating bananas daily is an excellent way to replenish pottassium, hope this answers your question and if it doesn't apologies.
Mechanically speaking, the "Surf's Up/Hang Loose" hand symbol uses the thumb and pinky fingers extended with the other fingers folded onto the palm. The Satanic hand symbol usually uses the fore finger and pinky extended with the other fingers folded onto the palm.
Addition is like counting on your fingers. If you hold up two fingers on you hand, then you put up two more fingers, you don't say I have 2 fingers up and now i put up two more so i have two fingers up doubled, you say I have four fingers up. Like adding, counting on your fingers is exactly the same. For instance. two plus two if four so on your fingers you can put up two fingers and then put up two more and have four. I hope I helped you!
