Mr. X’s presentation of chronic low back pain exacerbated by recent activities suggests a flare-up of his pre-existing musculoskeletal condition

QUESTION

Mr. X, a 42-year-old male presents to your primary care practice today complaining of low back pain.

History – Mr. X states that he has had chronic low back pain since he had a skiing accident about 10 years ago. Three days ago, he felt a pulling sensation in his lower back after moving some boxes. The pain intensity increased over the subsequent 24 hours and is now steady, aching in nature, at 3-4 out of 10. Mr. X also has Type2 diabetes, which is well controlled on metformin with a HGA1c of 5.6. He has a history of DVT 4 months ago for which he takes Coumadin, INR is WNL. He is followed by a specialist for this problem. He recently started taking two OTC products; kava kava for what he describes as “anxiety” and CoEnzyme Q10 on the advice of a friend.

Social – Mr. X is a smoker, 1 pack per week for 15 years. No alcohol or drug use. He is employed as an accountant and has medical insurance. He is divorced.
PE/ROS – Complains of low back stiffness and pain on movement with occasional spasms related to moving in certain directions. You note he has mild difficulty getting onto the exam table but gait is normal. He denies weakness/numbness/tingling of legs, no radiation, no change in bowel or bladder habits. BMI 27. All range of motion of the back is decreased by 25%. Straight leg lift is negative bilaterally, DTR intact. All other systems WNL.

Medications:

Metformin 1000mg ER one tab daily – Type II Diabetes controlled

Coumadin 5 mg. daily – Hx of DVT – Controlled

Kava Kava 50 mg. tid – Self-medication for anxiety

CoQ10 – 200 mg. daily. – Self-medication for unknown reason

1. Provide a diagnosis for the patient and your rationale for the diagnosis
2. Provide a treatment plan specifically for this patient, pharmacologic and non-pharmacologic.
3. Comment on the use of OTC products in relation to Mr. X’s current chronic and acute disease diagnoses and medications. Include drug-drug interactions and side effect profiles.
4. Provide an education plan for Mr. X

ANSWER

Diagnosis and Rationale

Mr. X’s presentation of chronic low back pain exacerbated by recent activities suggests a flare-up of his pre-existing musculoskeletal condition. The history of a skiing accident and chronicity of his symptoms align with degenerative disc disease or lumbar strain. The exacerbation might be due to recent heavy lifting. His mild difficulty in movement and stiffness, along with decreased range of motion and negative straight leg lift, indicates a musculoskeletal origin. Mr. X’s diabetes and DVT history might contribute to his pain perception, but no neurological deficits suggest a less likely neuropathic etiology. The absence of bowel or bladder changes and his history rule out cauda equina syndrome. The diagnosis of lumbar strain aligns with his history, symptoms, and physical examination findings.

Treatment Plan

Pharmacologic

Nonsteroidal Anti-inflammatory Drugs (NSAIDs): Ibuprofen 600 mg every 6-8 hours as needed for pain and inflammation.
Muscle Relaxants: Cyclobenzaprine 5 mg at bedtime as needed for muscle spasms.

Non-Pharmacologic

Physical Therapy: Gentle stretching exercises and core-strengthening exercises to improve muscle support around the spine.
Heat/Ice Therapy: Alternating heat and ice application can help alleviate pain and reduce inflammation.
Lifestyle Modifications: Educate Mr. X on proper body mechanics, posture, and avoiding heavy lifting to prevent further strain.

OTC Products and Considerations

Kava Kava: Evaluate Mr. X’s anxiety symptoms and consider discontinuing if ineffective or if it interacts with other medications. Kava Kava can interact with Coumadin and exacerbate liver conditions.
CoQ10: Discuss the reason for taking CoQ10 and assess its necessity. It has minimal interactions with his current medications.

Education Plan

Back Care: Educate Mr. X on proper lifting techniques, maintaining good posture, and avoiding activities that strain the lower back.
Medication Safety:Emphasize potential interactions between OTC products and prescribed medications. Encourage discussing any new supplements or medications with healthcare providers.
Exercise Routine: Teach Mr. X simple stretching exercises and core-strengthening activities to improve back health.
Follow-Up: Instruct Mr. X to monitor his symptoms and adhere to the treatment plan. Suggest seeking medical attention if symptoms worsen or new symptoms arise.

By diagnosing and addressing Mr. X’s lumbar strain, tailoring a treatment plan, considering OTC product interactions, and providing patient education, the aim is to alleviate his pain, improve his quality of life, and prevent future exacerbations. This comprehensive approach targets both pharmacologic and non-pharmacologic interventions to enhance his overall well-being.
