Lower Spine Tightness: Is It Ankylosing Spondylitis? - Orthopedics

Spinal pain


Hello, Director Shi.
I have a concern that I've recently noticed.
Whenever I squat down, the area of my spine just above my lower back feels very tight and stiff, making it difficult for me to stay in a squat position for long.
When I squat, it feels like my spine is being stretched, and there is some discomfort—though not severe pain—but it does affect my daily activities.
Additionally, when I bend over to reach down, my hands can only reach my knees.
If I try to extend further down, I experience pain in the same area, and I feel like my bones are quite stiff.
Could this be ankylosing spondylitis, or is it another condition? I hope you can provide me with some answers.
Thank you very much!

Hello: Ankylosing spondylitis is particularly painful in the morning upon waking.
Symptoms tend to improve with slight activity; however, a hematological examination is necessary to confirm the diagnosis.
Please visit the orthopedic outpatient clinic for X-rays and further evaluation to make a differential diagnosis.
Thank you! Orthopedics.

More Info


Based on your description of symptoms, it seems you are experiencing significant discomfort and tightness in the lower spine area, particularly when squatting or bending forward. This tightness and pain can indeed be concerning, and it raises the question of whether you might be dealing with Ankylosing Spondylitis (AS) or another condition.

Ankylosing Spondylitis is a type of inflammatory arthritis that primarily affects the spine and the sacroiliac joints, which are located in the lower back where the spine meets the pelvis. It is characterized by chronic pain and stiffness, particularly in the lower back and hips. The symptoms you describe—tightness in the lower spine, difficulty squatting, and pain when bending forward—are consistent with AS. However, it is important to note that AS typically presents with a gradual onset of symptoms, often worsening over time, and may also include morning stiffness that improves with activity.

In addition to AS, there are other potential causes for your symptoms. For instance, degenerative disc disease, muscle strain, or even conditions like lumbar spinal stenosis could lead to similar feelings of tightness and discomfort. Given that you mentioned the pain is not severe but still affects your daily activities, it is crucial to consider all possibilities.

To further evaluate your condition, a thorough clinical examination by a healthcare professional is essential. This may include imaging studies such as X-rays or MRI to assess the condition of your spine and the presence of any inflammation or structural changes. Blood tests may also be conducted to check for markers associated with AS, such as the HLA-B27 antigen.

In the meantime, there are several strategies you can employ to help manage your symptoms:
1. Physical Therapy: Engaging in a structured physical therapy program can help improve flexibility and strength in your back and core muscles. A physical therapist can guide you through specific exercises designed to alleviate tightness and improve your range of motion.

2. Stretching and Strengthening Exercises: Gentle stretching exercises can help relieve tightness in the lower back. Focus on stretches that target the hamstrings, hip flexors, and lower back. Strengthening exercises for the core and back muscles can also provide support and stability.

3. Posture Awareness: Maintaining good posture while sitting, standing, and moving can significantly impact your spinal health. Be mindful of your posture throughout the day, especially when sitting for extended periods.

4. Heat Therapy: Applying heat to the affected area can help relax tight muscles and alleviate discomfort. Consider using a heating pad or taking warm baths.

5. Medication: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce inflammation and relieve pain. However, consult with a healthcare provider before starting any medication.

6. Regular Exercise: Engaging in low-impact activities such as swimming, walking, or cycling can help maintain overall fitness and reduce stiffness.

If your symptoms persist or worsen, it is crucial to follow up with a healthcare provider for a comprehensive evaluation and tailored treatment plan. Early diagnosis and intervention can significantly improve outcomes for conditions like Ankylosing Spondylitis and other musculoskeletal disorders. Remember, managing symptoms effectively often requires a multifaceted approach, including lifestyle modifications, physical therapy, and possibly medication.
