There are several different root causes of sciatic pain, however they all involve irritation of the sciatic nerve, either through compression, kinking or physical trauma. Some of the most common causes include: A lumbar herniated disc: This happens when a disc in the spinal column "spills" out from its original place. This herniated disc comes in contact with the sciatic nerve, compressing it and causing pain and irritation. 'Degenerative disc disease: This condition is usually associated with aging. As the spinal disc ages, it weakens and may partially collapse leading to compression of the sciatic nerve. Piriformis syndrome: This is when the piriformis muscle (located in the buttocks) compresses the sciatic nerve. Lumbar spinal stenosis: This occurs when the spinal canal narrows in size, pushing its content outward and causing a kink in the sciatic nerve. 'Abnormalities in the spine: Anything abnormal in the structure of the lumbar spine may lead to sciatica. This may include infection, injury, tumor, internal bleeding, bone fracture or muscle weakness. The primary symptom of sciatica is pain. The pain may be felt along the length of the sciatic nerve, which runs through the lower back, buttocks, hips and legs. Because of the sciatic pain, the patient may have difficulty of moving, bending and walking. An accurate diagnosis of sciatica is important, as this will help the doctor to determine how the condition should be managed. The process for diagnosing sciatica will usually involve the follow: A physical examination: A physical examination may be performed, involving the straight-leg-raise test. The doctor will ask you to lie down and raise your leg slowly. The doctor will note the point at which pain is felt to determine which part of the sciatic nerve is affected. X-ray: An x-ray may be ordered to rule out fracture of the spine. MRI and CT scans: These may be prescribed by your doctor to aid in diagnosing sciatica. Detailed images of the lower back are created to learn more about the problem. Additional tests: Other nerve tests may be performed to confirm the diagnosis.These may include: velocity studies, electromyography, myelogram and evoked potential testing.

Bleaching is a very powerful method of removing hair color. However, because bleach is harsh on hair, only bleach if you've tried other methods. You should also get bleaching done at a salon by a professional. Usually, you will have to add hair dye over the bleach to return to your natural hair color. Another less harsh option is to do a bleach wash, which is when you mix shampoo with bleach. Some methods of hair removal can be harsh on your hair, leaving it dry. If you've removed the dye yourself, but your hair feels brittle, get a hot oil treatment at your local salon. This can help revitalize your hair. If hey don't offer hot oil treatments at your salon, then ask for a deep conditioning treatment. If all else fails, see a stylist. They can remove the hair dye in a professional setting. However, this is often costly. It makes sense to attempt to remove the dye yourself first before going to a salon for help.

You can purchase stage makeup packaged in a color wheel with the primary colors you'll use to make your black eye. Make sure the color wheel you get has dark, earthy tones of yellow, purple, red, and green because these will make your black eye look more realistic. Some brands, like Ben Nye and Mehron, sell a color wheel called a "bruise wheel" which is perfect for creating a black eye. You can buy stage makeup color wheels online or at local costume stores. Take a makeup sponge, dab it in the red color, and apply it around your eye. Follow along the bone of your eye socket and make sure you get into the creases and the ridge between your eye and nose. The base layer needs to be light and you should be able to see your skin through it. This layer will help the rest of the makeup adhere to your skin. Use a clean part of your makeup sponge to dab the purple color of your color wheel and apply the color around your eye in small amounts at a time. Start at the outer edges of your eye and work towards the center, making sure you apply the color to the ridges and creases around your eye. Real black eyes are splotchy and inconsistent, so don't apply your makeup to form an even layer of color. Use very small amounts of yellow and green to accent the bruise and make it look deeper and more realistic. Take a clean part of the sponge and dab it in the yellow color and apply it around your eye, then dip the same part of the sponge in the green color to give the green a yellowish tint. To finish your black eye and make it look realistic and seamless, take your makeup sponge and lightly blend along the lines where 2 colors meet, but don't blend all of the colors together.
