Be seen: There are many possibilities, and the lump near your elbow may not be connected with your other complaints. A pinched nerve in the neck can cause pain down the arm. A problem in the shoulder such as a rotator cuff problem can cause shoulder pain with difficulty raising the arm. Many more possibilities. A detailed exam would go a long way in determining the likely diagnosis, be seen.
