pain in shoulder and numbness in right arm

I have pain in my right shoulder that goes down the side of my right arm along with numbness from above my elbow down to my thumb.

I have the same exact thing! I will wake up every morning, with my right arm numb, even though i always sleep on my back, and my arm are just laying on my side, and even when i have my arm on my stomach and my elbows are bended it becomes numb too. Then with my shoulder, it hurts when im sitting or lying down straight.

But i think this is because of what im doing in school , because i am a culinary student, and i do a lot of stirring and heavy lifting, and hours on my feet...so i dont know if this is the reason, cause i never did get numbness before i started school...

I have the exact same thing, pain in my right shoulder, elbow and numbness in my arm, tingling in my right hand, this has just started 3 weeks ago, perfectly healthy. Now my wife has the same symptoms, does anyone know what it could be. It is only on our right side. Thank you.
