- A 59-year- old woman has been told by her orthopedist that the preferred treatment for her debilitating pain in both knees is knee replacement surgery. She agrees to have the surgery in one month when she will have time for rehabilitation. In the interim, the physician prescribes a medication for pain relief and to reduce inflammation. The woman is otherwise healthy, takes no medication, and has no known drug allergies. The physician decides on a nonsteroidal anti- inflammatory drug that has a high affinity for cyclooxygenase-2 (COX-2) and no affinity for COX-1. Compared to other NSAIDs, this drug is less likely to cause:
- A 69-year-old male presents to your office complaining of pain in his neck that extends bilaterally over his shoulders. He also complains of an aching sensation in both of his arms and loss of fine motor control of his hands. This has been progressing over the past six months.

- A 54-year-old male construction worker has had low back pain for about two months. He has had previous episodes of low back pain.

- A 42-year-old nurse presents to the office to see if OMM can be helpful for her long-standing foot pain.

She sustained multiple fractures at that time and the injury healed subsequent to multiple surgeries. There is no back pain and no pain in the legs. She is currently on morphine 60mg every twelve hours. Physical examination reveals relatively normal lumbar range of motion, normal straight leg raise, and reveals normal muscle tone, strength and sensation throughout both lower extremities. The foot and ankle are painful to touch on the surface. There is decreased range of motion of the ankle with erythema and skin dystrophic/atrophic changes. Which of the following pain management approaches is indicated:

- A 64-year-old school superintendent with known rheumatoid arthritis presents to the office with a recurrent episode of significant hand and wrist pain after having been virtually pain-free for about eight months on DMARD therapy as closely monitored by her rheumatologist.

What would be the best explanation, based on the article by D. Marcus: "Treatment of Nonmalignant Chronic Pain?"
