The sciatic nerve leaves our lower back and goes to the buttocks and back of the leg. So, compression of the sciatic nerve will cause pain in the buttocks, back of the legs or calves. When this happens it is called sciatica leg pain.
Causes of Sciatica Leg Pain
The most common cause of sciatica leg pain is a bulging disc. Discs are cushions that are spaced between our vertebrae. They are made of a gel placed in a capsule. That capsule might tear or bulge into the space between the vertebrae. But, that is also where the nerves leave the spinal canal. So, when a disc bulges, it might press on a nerve.
There are other causes of a compressed sciatic nerve. For instance, a fracture in a vertebrae or an inflammation of the tissue around it.
Sciatica and Night Leg Pain
Many people will feel sciatica leg pain more at night. The reason is position. In fact, finding a comfortable position to lay in is not easy. This is because many positions will increase the pressure on the nerve. Practically, that is why this is a cause of night leg pain.
Diagnosis
The first step is to examine the patient. Lifting the leg in certain positions will recreate the pain. Once we suspect sciatica, the next step might be imaging. For instance, an MRI of the lower back. The problem with this kind of imaging is that many people will have bulging discs, but will not actually have sciatica leg pain. So, working with a knowledgeable clinician is important.
Who Makes the Diagnosis?
The types of doctors who have knowledge in sciatica are orthopedic surgeons, physical medicine doctors and rheumatologists. Of these, think about starting with the physical medicine doctors.
You may have never heard of physical medicine doctors. Another name is physiatrist. These physicians are great in diagnosing orthopedic conditions and in treating them without surgery. Actually, types of treatments they offer include physical therapy, rehabilitation and special injections. Only if these fail, they will send you for surgery.
Treatment
Treatment includes physical therapy, injections to reduce inflammation and sometimes surgery.
