Ankylosing Spondylitis Symptoms and Diagnosis | This AS Life

The journey from first noticing ankylosing spondylitis symptoms to an eventual diagnosis is different for every patient. Some are diagnosed quickly, for others it may take far, far longer. In the past, the average time to diagnosis with AS was around 8-10 years.Hopefully  we can continue to reduce this delay, but currently many patients still go undiagnosed and untreated for a long time, seeking help from GPs, physios and other physicians without ever seeing a rheumatologist. 

 

What’s your body telling you?

The symptoms of AS can range from mild-to-moderate right through to severe. One of the most common is lower back pain, which improves with exercise and gets worse with rest. This pain can often be serious enough to wake people at night and restrict their movement during the day. However, back pain of this type is so often due to injury or degenerative arthritis that patients won’t usually suspect AS unless they’re already familiar with the condition.

 

Finding relief

Self-treatment with pain relievers such as paracetamol and anti-inflammatories is the first step for many patients. These offer varying degrees of relief, from simply blocking the pain to helping reduce the inflammation that causes it. Physiotherapy is also often tried, both by patients with unattributed back pain and those diagnosed with AS. This can be effective in reducing some of the discomfort of AS because it improves flexibility but it’s unlikely to offer a complete solution. 2-3

 

There will be good days and not so good days as symptoms vary but having others around you who know your story and can provide help is often the key to a happy AS life

Call in the professionals

Patients usually first go to their GP with symptoms closely resembling persistent back pain. GPs see a lot of back pain but, again, will most likely suspect injury or osteoarthritis rather than AS as the cause.

With this in mind, GPs’ investigations often start with x-rays and/or simple pain relief. One of the issues with this approach is that the damage from inflammation in AS cannot easily be seen on x-rays, so scans can appear normal for years, delaying diagnosis.

 

To see the inflammation of AS you need to use an MRI scan,but this type of scan is both expensive and difficult to access so unlikely to be used this early. This means it’s very important for patients at this stage to ensure their GP is keeping an open mind regarding their condition, even in the presence of a clean x-ray.

Specialist care

In addition to their GP, patients may see a range of specialists for treatment of other conditions associated with AS. Hip or knee involvement may need an orthopaedic surgeon; eye inflammation will involve an ophthalmologist – gastroenterologists or dermatologists may even be called in to help deal with possible bowel inflammation or psoriasis.

 

However varied their journeys may be, most patients will eventually end up seeing a rheumatologist like myself. We’ll take an in-depth family history and usually request blood tests, x-rays or MRI scans to confirm the presence of AS. Once the results of these tests are back we can make a decision on the right next step - diagnosis, watching-and-waiting or referral to another specialist.

Whatever the symptoms of your AS, your GP and rheumatologist will want to monitor your disease to make sure that it is treated appropriately and that any complications or issues with treatment are resolved swiftly.

Each patient’s journey is different because each person is different

Getting the right help

With a confirmed AS diagnosis, and alongside proper medication, tailored physiotherapy comes into its own as an effective form of AS relief.3 Though it can be difficult to access, multiple sessions aren’t necessarily required - a good set of ankylosing spondylitis-specific exercises that you can do at home regularly is sufficient to benefit physical function.

 

Support and exercise groups can also help lighten the load a little. These can often be found through local charities, patient associations or even online. Knowing that there are other people out there with the same condition, grappling with the same issues, can be very reassuring and supportive.

Whatever your AS journey, involving not just your doctors but patient groups, charities, friends and family, even work colleagues, can be really beneficial. There will be good days and not-so-good days as symptoms vary, but surrounding yourself with people who know your story is often the key to a happy AS life.
