5. Subjects who at screening are not on chronic analgesic/anti-inflammatory medication and have a VAS pain score of > 40mm and < 90mm or subjects who are on chronic analgesic/anti-inflammatory medication at screening and have a VAS pain score of > 30mm and < 90mm, indicating a lack of adequate and sustained response to current therapy.

6. At baseline, after all analgesic/anti-inflammatory medication has been discontinued for 2 weeks (including withdrawal from acetaminophen rescue medication for 24 hours prior to screening) should have a VAS pain score of > 40mm and < 90mm.

11. Subjects who have a compromised mental capacity or who may be unable to legally comprehend the details and nature of the study.

13. Subjects who in the opinion of the investigator are unlikely to adhere to the study protocol or to complete the study as planned.

14. Subject has a chronic pain condition (chronic low back pain, chronic headache, fibromyalgia, chronic osteoarthritis, chronic rheumatoid arthritis etc.) that could confound the shoulder pain response to the study medication(in the opinion of the investigator)

15. Subject is using and is not willing to discontinue opioids, topical counterirritants (eg methylsalicylate or capsaicin) or the use of orthopedic devices for the study shoulder.

16. Significant liver impairment (defined as liver enzymes elevated more than three times the upper limit of normal) or significant renal impairment (defined as a serum creatinine level greater than twice the upper limit of normal.
