Hi!
Pain in the shoulder in the front aspect along with arm pain in the front region (known as anterior shoulder pain) can be due to rotator cuff injury, injury to labrum, arthritis, bicep tendon injury, shoulder dislocation, thoracic outlet syndrome (TOS), pinched spinal nerves in the cervical spine, fracture of the upper arm bone etc. You need to be examined by an orthopedic specialist and may need X-ray and MRI of the shoulder joint, cervical spine etc for confirmed diagnosis.
probably Scalene Myofascial Pain Syndrome. When scalene muscle is the cause of pain, the pain is referred from neck to (either all or a combination of) chest, inner lining of scapula (shoulder bone), shoulder, posterior and lateral sides of the arm right up to the thumb and index finger. When this muscle shortens, this can press on brachial plexus (bundle of nerves and blood vessels in the armpit) and the subclavian artery and can compress or irritate these structures and cause symptoms such as abnormal sensation, cold extremity, spasms of pain, and lymphedema (swelling of lymph channels causing swelling of arm or leg) in the involved extremity. Treatment is by physiotherapy that involves indentifying the trigger points, and massaging them, and other exercises to relieve the muscle tension. This is a major cause of TOS. Other than this it can be inflammation of veins or phlebitis, inflammation of lymph channels or lymphangitis, deep vein thrombosis or compartment syndrome.
Since a confirmed diagnosis cannot be given on net please consult your doctor regarding these possibilities. Hope this helps. Take care!
