Answer by  Will65 (73)

The throbbing of you arm can be caused by a couple of things. They may include stress, maybe you lifted something heavy or maybe it's throbbing because of irregular muscle contractions.

The throbbing pain may be due to a heavy work to the arms such as lifting heavy weights or even writing work for a long time etc. There is also a chance for accidental damage to the arm without your knowledge while you were sleeping.

If your pain is in both arms, there can be compression of nerves by cervical spine or brachial plexus. If pain is in the internal side of left arm, it can be related with ischemia of heart. It can also be due to simple neuritis.

I used to have this when I had 2 ruptured discs in my neck. What happens is that the discs push on the nerves causing pain to go down in the arm on the side where the protrusion is. Some experience numbness in their hand as well. You should get an x-ray and and MRI done.
