It might have a sore, broken bone or have twisted it's right arm. You need to keep on eye on your hamster to make sure that it does not get worse. Good luck:)
with your stronger arm ex if you are right handed use your right arm grab the arm of the microscope and use your other arm/hand at the base/under it
No !!!
You should get a chain on your wrist but it looks like it connects to each other and one should get it on the right arm and the other on the left arm.
Your arms should follow through parallel to you body. (Assume right handed) Your left arm should pull down from in front and above your head before contact, with your right arm swinging through along a similar path in front for contact. Arm path should be an 'over the top' and not an an angle.
just pet him til he comes down
Most likely. Some bone could have chipped off and this might cause a tiny amount of internal bleeding. That's why it looks so swelled up. Hamster, and other rodent's bones', are very delicate. Bring the hamster to the vet immediately!
Most of the time your adrenaline will not allow you to feel the injury. I strongly suggest going to the E.R. as it is by far the best decision at the moment for you.
When you are placing or retrieving an item from a table, you should use the arm away from the guest. If you are on the right of the guest, you should be using your right arm, as if you are "hugging" them. Same goes for the left. You do not want to put your body between you and the guest.
men always on there left
The right arm
The proper way to remove the pitman arm is to use a pitman arm puller. If you do not have one, you can split the arm with a cutoff wheel near the tapered splined hole to reduce the strength of the arm and it should fall right off.
