First of all, it is clear that the pain inside the bone described by the patient is not necessarily a medical bone pain, but may include neuropathic pain, muscular pain, strain pain, and radiating pain that may be caused by other internal medicine. The most common orthopedic diseases are: 1) muscle strain can cause pain; 2) strain at the tendon stop can also cause pain; 3) tumors can grow inside the muscles, which can also cause pain; 4) tumors on the bones can also cause pain; 5) cervical spondylosis, which compresses the nerve roots and radiates pain to the arm. So it is important to seek medical attention for arm pain, to clarify what causes the pain, and then to treat it accordingly.
