Patient Consultation

OSTEOPATH: Hello, how may I help you today? I have been looking forward to understanding your concerns better.

PATIENT: Hi, I've been experiencing some persistent back pain for the past few weeks. It has been bothering me, especially during my daily activities.

OSTEOPATH: I see. Since when have you been feeling this discomfort? I want to ensure that we address this properly.

PATIENT: It started about three weeks ago. I thought it would go away on its own, but it has only gotten worse.

OSTEOPATH: That sounds challenging. During this time, have you noticed any specific activities that aggravate the pain?

PATIENT: Yes, sitting for long periods has been particularly uncomfortable. I have also felt some stiffness in the mornings.

OSTEOPATH: Thank you for sharing that. Have you had similar pain in the past, or is this the first time you have experienced it?

PATIENT: I have had mild discomfort before, but it has never lasted for this long. Since the pain started, I have been struggling to sleep well, and I have felt quite fatigued during the day.

OSTEOPATH: That must be frustrating. Have you been doing anything to manage the pain during these past three weeks?

PATIENT: Yes, I have been trying to stretch and use a heating pad. I have also taken some over-the-counter pain relievers, but they haven’t been very effective.

OSTEOPATH: I understand. Have you had any injuries in the past that could be related to your current discomfort?

PATIENT: Not that I can think of. However, I have been working from home for the past year, and I have been sitting for longer hours than usual.

OSTEOPATH: That could be a contributing factor. Since you started working from home, have you changed your workstation setup?

PATIENT: Not really. I have been using my dining table as a desk, and I don’t think my chair provides much support.

OSTEOPATH: That makes sense. Poor posture during extended sitting periods can lead to muscle strain. Have you noticed any pain radiating to other areas, like your legs or shoulders?

PATIENT: Yes, I have felt some tension in my shoulders and neck, especially during the afternoons. I have also had occasional tingling sensations in my lower back.

OSTEOPATH: That is important to note. I have been treating similar cases, and I believe we can work together to find a solution. Before we begin, I will conduct a thorough examination to assess your condition. Please undress down to your undergarments so I may better examine you.
