Keep track of your symptoms!
Since Ankylosing Spondylitis is a gradually progressing disease, it is important for you to know how to identify that your condition is worsening.
Progression can be easily identified if you become aware of the subtle signs that your body gives you. A few signs are listed below:
Increasing stiffness in the morning
Inability to do daily tasks with ease
Notify your doctor if the duration and intensity of any of these symptoms are increasing. It could be a reflection of disease progression, manifesting as bone growth at spinal vertebral edges leading to spinal fusion over time.
Avoid the unwanted consequences of Ankylosing Spondylitis.
