Sciatica

What is sciatica?

Sciatica is pain caused by irritation of the sciatic nerve. The irritated nerve causes pain that runs down your leg from your lower back or hip.

How does it occur?

The sciatic nerve is formed by a group of nerves that run from the lower spine down the leg to the foot. Anything that irritates the nerve can cause sciatica. The most common causes are:

  • overuse of your back (lifting something that is too heavy or doing work that uses your back much more than you are used to)  

  • injury to your back (slipping and falling, or having something hit your back).  

Overuse or injury can cause muscle tension or spasm, back sprains, ligament or muscle tears, or joint problems, all of which can irritate the sciatic nerve.

Low back pain and sciatica can also be caused by infections, tumors, a ruptured (herniated) disk in your back, osteoporosis, spondylosis (hardening and stiffening of the spine), or spinal stenosis (a narrowing of the spinal canal that squeezes the spinal cord and nerves).

What are the symptoms?

  • The main symptom is pain that shoots down from the lower back and buttocks to your leg.  

  • You may also have numbness or tingling in your leg.  

  • Sometimes your leg muscles are weak.  

How is it diagnosed?

Your Reddy Urgent Care healthcare provider will ask about your symptoms and examine your back. If your provider thinks you might have an infection or a bone disease, you may have some lab tests or X-rays, a CT scan, or an MRI. Most people do not need X-rays or other types of scans in the early part of their treatment. If the pain does not get better in a few weeks, or if the symptoms get worse, then special tests may be needed

How is it treated?

Most people with low back pain and sciatica get better no matter what they do.

Acetaminophen may help decrease your pain. Often nonprescription nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, and naproxen can help relieve pain and inflammation. These NSAIDs may be bought with or without a prescription. Check with your healthcare provider before you give any medicine that contains aspirin or salicylates to a child or teen. This includes medicines like baby aspirin, some cold medicines, and Pepto Bismol. Children and teens who take aspirin are at risk for a serious illness called Reye’s syndrome. NSAIDs help reduce pain and swelling but may cause stomach bleeding and other problems. These risks increase with age. Read the label and take as directed. Unless recommended by your healthcare provider, do not take NSAIDs for more than 10 days for any reason. Talk to your healthcare provider about whether you should take these medicines.

Your Reddy Urgent Care provider may prescribe stronger pain medicine or other types of medicines. Your provider may prescribe oral steroids or you may be given a steroid shot into your spine to control pain and inflammation.

Your Reddy Urgent Care provider may also suggest physical therapy. A program of gentle stretching and exercise may speed your recovery.

If you keep having symptoms, you may need to have surgery for a ruptured disk. However, most people who have ruptured disks do not need an operation.

How long will the effects last?

People who have sciatica with back pain recover more slowly than people with other kinds of back pain. However, you will probably begin feeling better within a few days of a back strain or injury if you don’t strain your back again and if you take some medicine for pain and inflammation. Often the pain is gone in a week or two.

How can I take care of myself?

  • If you have low back pain and sciatica, make sure you do not overuse your back. Strict bed rest is no longer recommended. It is better to do your usual activities but:  

    • o.Avoid lifting more than 5 pounds.  

    • o.Avoid frequent bending or other activities that make the pain worse. 

  • Ice packs or a heating pad may help reduce pain. Don’t sleep on a heating pad because it could cause burns.  

  • When you sleep on your side, put a pillow between your knees. If you sleep on your back, put a pillow under your knees. Try to avoid sleeping on your stomach.  

  • Change your position often throughout the day. Try to alternate sitting and standing. If you must stand for a long time, try putting one foot on a low stool.  

  • If you smoke, stop. Smoking decreases blood flow to muscles and disks in and around your spine. Injuries take longer to heal in people who smoke.  

  • Come to Reddy Urgent Care right away if:  

    • o.You have numbness or tingling in the inner part of your thighs.  

    • o.You have new or increasing weakness in your legs. 

  • Call Reddy Medical Group for a follow-up appointment if:  

    • o.The pain is not getting better.  

    • o.You have new symptoms. 

How can I help prevent sciatica?

If you have had back pain and sciatica, you are likely to get it again. To help keep from having it again:

  • Lose weight if you are overweight.  

  • Do regular aerobic exercise to keep your back and abdominal muscles in shape (this can be as simple as walking),  

  • Do stretching exercises before participating in activities.  

  • Learn to lift properly. Bend your knees and hips and keep your back straight when you lift a heavy object.  

  • Practice good posture. Stand with your head up, shoulders straight, chest forward, weight balanced evenly on both feet, and pelvis tucked in.
