arm
If it is painful, my best guess would be a dislocated shoulder. That allows you to keep movement of your elbow down, but not your shoulder.
Well when I experienced staff infection on my arm it did not hurt at all. It depends on the location of the body and the size of the infection.
I kno you really dont want to, But get to a f'in hospital. Or just suck it up, and wait it out. good chance you might be allergic. and that could mean big problems. You can try and put a really hot towel around arm. this will help release it.
The way you could measure the mass of your arm is to place it in a tub of water that is filled to the brim, and then measure the amount of water that is displaced (spilled over) after you submerge your arm. That would give you a close estimate. But, when you punch, it is more than the mass times acceleration that is delivered, like in Newton's Second Law of Motion. If you watch Bruce Lee punch, you can see that he used his whole body and thrust his hips into the punch.
they are goose Bumps. :)
check your pitman arm and idle arm
Sounds like herpies zolster
Not really. I have them as well and I am a very fit teenager.
bushings (control arm)
Relax darling, those little bumps are common during the change of season to the summer. I'm guessing now your sweat glands are working twice as hard and your skin still has to adapt. Small tip, stop popping them, scrub up, and don't put lotion, I'll be cleared out in no time.
You definitely could have painful swollen veins in your arm after having your blood drawn many times. This happens frequently.

No it doesn't, done it many times. Now, if you staple your penis, that is really painful. BUT! Your arm is fine.
It sounds like a heat rash, you should check it out Benadryl will help.
The best thing that you can do is exfoliate in the shower. Use a body exfoliant with salicylic acid in it. These bumps are caused by dry skin getting caught under the skin so try not to wear tight clothes that cover your arms, give them room to breath.
Its a rubber piece that holds the control arm to the frame of the vehicle it is round like the control arm to allow the arm to flex. (The control arm holds the wheel to the frame and uses the control arm bushing to flex over bumps while holding the wheel vertically and keeps your tires wearing properly).
