Extreme pain in rt shoulder. cannot lift up more than a little. beginning to hurt from bicep down. hand can go numb, drop things.

Shoulder pain: And X-ray of shoulder is needed as well as good physical exam to delineate shoulder joint problem or neck problem referred to the arm

Possible neck issues: It could be related to your neck, especially since you are having numbness in your hand and dropping things. However, I think your shoulder should be evaluated too for possible bursitis or possible rotator cuff issues.
