“Sciatica” is an old world term that refers to leg pain felt down the back of the thigh into the calf and foot. What about thigh pain? What about buttock pain? Unfortunately, “sciatica” has been wrongly applied to all types and locations of leg pain. In 1948, the use of the word “sciatica” was declared “unhelpful” by a leading orthopedic specialist because it is limited to a certain location and really does not address the origin of the pain. Over the years, many older medical terms like sciatica have become archaic as the newer research technologies give doctors clearer definitions and a better understanding of the human body. Leg pain that comes from the low back is most accurately categorized as referred pain or neurogenic pain. These terms apply to all locations and address the origin of the pain. With these newer terms, the antiquated word, “sciatica”, has no place in the modern world. Sally has been waking up with right ...
Abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs can also be looked at with ultrasound.

How the test is performed
An ultrasound machine creates images that allow various organs in the body to be examined. The machine sends out high-frequency sound waves, which reflect off body structures to create a picture. A computer receives these reflected waves and uses them to create a picture. Unlike with x-rays or CT scans, there is no ionizing radiation exposure with this test.
You will be lying down for the procedure. A clear, water-based conducting gel is applied to the skin over the abdomen. This helps with the transmission of the sound waves. A handheld probe called a transducer is then moved over the abdomen.

Sometimes cancer cells spread to other parts of the body. When this happens, the breast cancer may be described in a few different ways: metastatic, advanced, or stage IV. The term "metastases" refers to specific areas of spread, such as bone metastases.
If you have signs or symptoms of metastases, your doctor will likely use local treatment (treatment directly to the cancer area) to relieve the symptoms and to control the disease at that spot. Radiation can shrink and help control specific spots where the cancer has spread. Radiation can help:
lower the risk of broken bones in areas that may be weakened from cancer
improve breathing by opening up a blocked airway
take pressure off a pinched nerve that might be causing pain, numbness, or weakness
The radiation dose and schedule for metastases depends on a number of factors, including:
the urgency of the situation (pain, loss of function, size and location of the metastasis, for example)
any previous ...
