I woke up yesterday with extreme shoulder pain. It hurts to lift my arm up and shoots down to my elbows. I feel a bump on my shoulder. I put shoulder cream but it doesn't seem to help. What is it and how to cure at home. Should I see a dr.

Did you lift anything heavy the day before?
Since it shoots down to the elbow there might be some nerve damage involved. I would go see a doctor

No I just woke up with it
