Sciatic Nerve Damage

Friday, March 16th, 2012

Sciatica, which is the condition caused by sciatic nerve damage, is characterized mainly by a sharp, shooting pain from the hip or buttocks area down to the toes. This pain is usually worsened by moving the leg, bending over at the waist or sitting down. The pain is similar to a pinched nerve.

If the sciatica is caused by pressure on the nerve, such as from a slipped disc, numbness in the leg may occur. While this numbness isn’t necessarily a problem, it can cause other problems. These include imbalance, which can lead to falls. Numbness in the leg can also cause that leg to be weaker than the other leg, which makes lifting even light objects difficult.

A dull lower backache is a less common symptom of sciatic nerve damage. This pain is either a result of the sciatic nerve being compressed or by other conditions, such as a herniated disc, that is often found in conjunction with sciatica. This backache may come and go; however, it is more common at night after a full day of activity. This is usually because the sciatic nerve is swollen. Many doctors prescribe an NSAID or recommend taking ibuprofen or aspirin to reduce the swelling.

Because the sciatic nerve affects the foot and toes, foot drop and toe drop are common symptoms. Toe drop occurs when the big toe on the affected side becomes so weak that it is difficult to extend or contract it. Foot drop occurs when the ankle is weak and the foot ‘flops’ sometimes. This symptom is serious, as falls can occur as a result.

All of the symptoms of sciatica are unilateral, meaning they only occur on one side of the body. However, in some instances, such as pregnancy, symptoms can occur on both sides. In that case, one side usually experiences more pronounced symptoms than the other side.

Symptoms of sciatica can be painful and uncomfortable. However, they can be confused up with symptoms for another type of back pain. More often than not the actually discomfort of sciatica pain begins within the back leg. Symptoms of sciatica vary depending on the sufferer. Below are some common symptoms of sciatica.

  1. The lower leg or the shifting of feet may cause a feeling associated with a weak point and numbness.
  2. If lower-leg discomfort is actually worse compared to back pain discomfort.
  3. Agonizing or razor-sharp discomfort in the back and leg is experienced.
  4. Discomfort is mainly in a single area rather than all over the body.
  5. The pain is a long-lasting discomfort within the lower-leg, back, and buttocks.

If you are experiencing any of the above symptoms of sciatica you should see a doctor as soon as possible. They physician will first rule out acute medical causes such as tumors, internal bleeding, infection, or other chronic diseases such as diabetes. After these have been ruled out, the physical will continue the examination to determine the exact cause of sciatica.

The doctor may choose to do one of the following examinations:

  • Physical examination
    • Reflexes: wear or absent ankle-jerk reflex
    • Foot may be bend inward or downward with extreme difficulty
    • Reproduction of sciatica pain when the leg is lifted straight off the exam table.
    • Weakness of knee bending
  • EMG (recording of electrical activity in muscles): needles are strategically placed along the nerve passage, and the electrical conduction is recorded
  • Radiological exams: X-rays, MRI’s CAT scans, etc. may all be included as part of the examination process.

Above are some of the common symptoms of sciatica and what may occur during an examination for diagnosing sciatica pain. When diagnosed, the discomfort of the symptoms of sciatica can be treated.

 

Sciatica Diagnosis: Making Sure its Accurate

Thursday, February 9th, 2012

Sciatica diagnosis is characterized by a persistent severe pain in your spine that travels all the way down the back of your leg. However, this is not a condition you can self diagnose, you must see a doctor in order to get an accurate sciatica diagnosis. During your sciatica diagnosis the doctor may ask you to point out the distribution and intensity of your pain in order to better understand your problem. For the most accurate sciatica diagnosis the doctor may administer tests such as an MRI, CT scan, or X-rays.

The types of sciatica diagnosis tests listed above are conducted on an individual basis, depending on the seriousness of the experience pain. Sciatica pain is felt from low back region to the area behind the tight, and often radiates to below the knee. The seriousness of sciatica discomfort can be so severe that people often believe that it has resulted due to a specific large trauma, whereas it is actually a combination of multiple small trauma incidents.

It is difficult to diagnosis sciatica because there may be many medical conditions that cause this type of pain. For example, lifting heavy objects or an injury might cause pain in your back, thigh, or legs. Therefore, it is important to find the exact cause of the pain in order to avoid the wrong sciatica diagnosis.

Sciatica pain may be caused by situations not related to the lumbar disc and bad posture may lead to pain similar to sciatica. Normally, sciatica results because of pressure exerted by the lumbar disc on the sciatic nerve. Any type of irritation on the sciatic nerve can create sciatica pain. Most causes of sciatica can be attributed to irritation of the sciatic nerve by infection, tumors, internal bleeding or excessive pressure exerted by a bone.

During a physical exam for sciatica diagnosis, the patient is normally asked to lie down on an examination bed facing upward. His or her affected leg is raised to different heights to accurately determine the point of compression. He or she is then asked to rotate their hip joint. This is done to establish the exact point of pain and for assessing the hip muscles. This movement will help indicate the position where there is a possibility of a nerve being pinched. If symptoms are serious enough to suggest surgery, a physical exam will be followed by further investigative procedures.

If you are scheduled for a sciatica diagnosis be sure to be prepared to tell you doctor the exact location of your pain. Generally a severe pain that travels from the spine to the lower leg characterizes sciatica diagnosis. Keep in mind that sciatica diagnosis varies depending on the person so it is best to consult your doctor!
