How to Diagnose a Herniated Disc

Recognizing Symptoms

Pay attention to pain in your lower back. Most cases of herniated disc are in the lower back. You will notice a sharp or dull pain that may improve after a few days. Your pain may go away in your back but move into your leg. You may not experience any pain with a herniated disc, but your doctor may have trouble diagnosing your condition if you don’t.

Watch for pain that moves from your lower back down your leg. As the herniated disc slides between your vertebrae, it can press down on your nerves. This may cause pain in your leg, all the way down to your foot. You may feel pain just in your leg or all the way from your back down to your leg. This is called sciatica.

Check for numbness, weakness, or tingling in your leg or foot. Because the herniated disc may press on your nerves, it could cause symptoms in your leg and foot. These symptoms usually occur quickly after the initial injury happens and can worsen if left untreated.

Seek medical attention if you have bladder or bowel control issues. Most patients will not have bladder or bowel issues, but they can be caused by a herniated disc pressing on the nerves that manage your bladder or bowel. If this happens, you should seek emergency care. A doctor can help alleviate your symptoms.

Know your risk factors. While anyone can suffer a herniated disc, some people are at an increased risk. Being aware of your risk factors can give you a better idea about whether or not your symptoms could be a herniated disc. You may be at a higher risk if you: Are overweight or obese. Are a smoker. Lift with your back instead of your legs. Twist your back while lifting. Have a physically demanding job that puts pressure on your spine. Drive often. Live a sedentary lifestyle. Are a man between the ages of 30 and 50.

Getting Medical Care

Make an appointment with your healthcare provider. Your doctor can determine if you have a herniated disc and prescribe treatment. Describe your pain to the doctor, including where you feel it. In most cases, your doctor can make a diagnosis of a herniated disk in their office, without invasive diagnostic tests. Even if other tests need to be done, they will not be painful.

Bring a thorough medical history. Make a list of the other conditions you have so that your doctor can rule them out as the cause of your symptoms. For example, osteoporosis can cause similar symptoms. Your doctor will also need to know your family history, as having a family member with a herniated disc increases your risk of having one.

Expect your doctor to check your back for tender spots. Your doctor will feel along your spine to look for painful areas. They will likely ask you to change positions or move around your legs so that they can get a better idea about where your pain is located and how it’s impacting you.

Allow your doctor to do a neurological exam. While it sounds scary, this is a non-invasive, painless office exam. Your doctor will check how well your reflexes work, as well as your muscle development. They will then check your balance and posture. Finally, they will check to see how well you feel sensations like pinpricks, touch, or vibration. The results will help the doctor determine if you may have a disc putting pressure on your nerves. A herniated disc can make it harder for your nerves to communicate with the rest of your body, so your body may have trouble registering pain or may get too many pain signals.

Do range of motion tests. The doctor will ask you to bend and move side to side at your joints. This will allow the doctor to see how limber you are and if you are able to move freely and without pain. If you have a herniated disc, it may affect your range of motion.

Perform a leg raise test. Your doctor will have you lie back on the table. They will slowly raise your leg until you start to feel pain. If you have pain while your leg is at a 30 to 70 degree angle, then you may have a herniated disc. Additionally, if you feel pain in the other leg, it could mean you have sciatica caused by a herniated disc. This test may not be accurate if you are over the age of 60.

Get an X-ray to rule out other issues. If your doctor is not sure that your symptoms are caused by a herniated disc, they may do an X-ray to rule out other health issues, such as a broken bone or a tumor. Herniated discs will not show up on an X-ray. The doctor can use an X-ray to look for pressure on your nerves and spine by injecting a dye into your body. This is called a myelogram. While the pressure on your nerves and spine could be caused by other conditions, it will help your doctor determine if you have compression on your nerves. Your doctor may also take a computerized tomography (CT scan), which takes a series of X-rays to create a more thorough image for the doctor to assess.

Undergo an MRI to locate the herniated disc and the nerves it’s pressing. An MRI lets your doctor get a closer look at your spine so that they can treat your herniated disc. Not only can they confirm the location, they can also determine how severe it is. While you will need to be still, the MRI will not be painful.

Expect nerve tests if your doctor suspects nerve damage. Usually, you will not have to undergo nerve tests. Your doctor may do these outpatient tests if they suspect you already have nerve damage, based on your reported levels of pain. Although the tests are not painful, they may make you a little uncomfortable. An electromyogram and a nerve conduction test will send electrical impulses to your nerves to see how well they respond. This lets your doctor look for damage to the nerves.

Treating a Herniated Disc

Rest for 1 to 2 days but not longer. Your pain should improve if you stay off your feet for 2 days. After 2 days, you shouldn’t rest for too long at once, as this could make your symptoms worse. Instead, get up and walk around every half hour. Slow yourself down so that you don’t over-stress your back. Don’t bend or lift anything. If an activity is causing you pain, then you should avoid it.

Take NSAIDs to cope with pain. If your herniated disc is causing you pain, over-the-counter NSAIDs like ibuprofen, Advil, naproxen, or Motrin may relieve it. Use them sparingly and only if your doctor approves them. If your pain is still severe, talk to your doctor about other pain relief options, such as prescription painkillers. If you’re having muscle spasms, your doctor may prescribe you muscle relaxers. Since medications can cause long-term effects or result in dependence, you should use as little as possible to manage your symptoms.

Ask your doctor about cortisone injections to reduce inflammation. Your doctor can lower the swelling around your vertebrae and nerves with corticosteroids. They will inject them into the area around your herniated disc to relieve some of the pressure. Sometimes your doctor will be able to give you oral corticosteroids to reduce inflammation, but it isn’t as effective as an injection.

Do physical therapy if your symptoms do not improve after a few weeks. Most people will see improvement in the weeks after beginning treatment. If you don’t, your doctor may recommend physical therapy. The physical therapist will teach you exercises to strengthen your lower back and core muscles.

Try spinal decompression therapy. Spinal decompression therapy is a nonsurgical procedure where the spine is stretched out to relieve pain. If you're interested in spinal decompression therapy, talk to your doctor or visit a trained chiropractor or osteopath. Studies on the effectiveness of spinal decompression therapy are limited.

Consider surgery if nothing else works. Very few people who have a herniated disc will need surgery, but your doctor may recommend it if nothing else helps your symptoms. The doctor will remove the part of the disc that is protruding. In rare cases, the doctor may need to fuse your vertebrae together to keep them stable or may implant an artificial disc. After surgery, your doctor will likely recommend physical therapy.

Manage your lower back pain. Back pain is no fun, but there are ways to manage the symptoms. You may not be able to get rid of it forever, but you can lower the amount of back pain you experience by giving your lower back some TLC. Get a massage. Do yoga. Visit a chiropractor. Get acupuncture.
