What would cause my arm to continually feel like it's asleep and wake me up with shooting pain? And it continues to have numbness throughout the day

Neck issue. This requires your doctor to see you. Don't sit on this. Sounds like a cervical spinal nerve root compression.
Nerve . It sounds as if there may be pressure on the nerves in your neck. It could also be pressure on the nerves by your first rib. You should see your family md for an MRI of your neck and either a neurologist or neurosurgeon to help work this out.
