Why am I dizzy and have neck/upper shoulder pain when raising arms?

Probably not related. There is a rare condition called "the subclavian steal syndrome" that causes dizziness when you raise and use your left arm. It can be ruled out on physical exam in the office. Have your doctor check you. Otherwise, the two symptoms are probably not related.
