Sciatica refers to any pain or compression of the sciatic nerve.  The sciatic nerve runs from the back of the pelvis and right down through the buttocks and both legs and ends at the feet. If something presses on the sciatic nerve it can cause a pain that runs from the lower back and down the leg; this pain can be mild to severe.

Sciatica

Causes of sciatica include slipped discs which can get temporarily moved out of place and then press on the sciatic nerve.  Acute sciatica is pain which lasts up to six weeks whereas chronic sciatica lasts longer than six weeks. Most cases clear up unaided but using painkillers, hot or cold compresses and exercise can help to alleviate symptoms. Sometimes there is a need to contact a physiotherapist especially for chronic sufferers.

Sciatic pain is different to back pain in that it also affects the legs.  Sciatica can cause weakness in the legs or feet. There is a rare condition which can cause sciatica and this is called Cauda Equine Syndrome.  This can lead to paralysis if left untreated as it can permanently damage the nervous system.  A sign of cauda equine syndrome is the sudden loss of bladder or bowel control and if this occurs immediate medical help should be sought.

Another cause of sciatica has been put down to general wear and tear.  This is why people over forty with jobs involving a physical activity are more prone to sciatica.

HIV, or human immunodeficiency virus, is the virus which can lead to AIDS. There are many ways to contract this virus, with the most common being through unprotected sex and the sharing of needles.

People who are infected with HIV may initially not realize there is anything wrong with them as they do not show any symptoms. Nevertheless, some people tend to develop some flu like symptoms which can last for several weeks. Some of these symptoms may include fever, tiredness, loss of appetite, aching muscles and joints, rashes and swollen lymph glands.

HIV Virus Structure

When the virus enters the body, it takes residence in white blood cells that are known as CD4 lymphocytes. The virus takes total control of these cells and starts producing billions of replicas of itself every day.

Once infection of HIV occurs, the body starts to attack the virus and because of this the virus cannot make any copies of itself. This in turn leads to a false sense of wellness as although one would still have HIV, the infected person will begin to look and feel better. Unfortunately, during this period the virus is still attacking the lymph nodes, which are the body’s immune system center.

During the course of ten to fifteen years, the HIV manages to kill so many of the CD4 cells that the body no longer has the ability to fight off infections. Once the CD4 cell count drops below a certain number (200 or lower per mL – the average is 600 to 1000) the sufferer is classed as having AIDS (acquired immunodeficiency syndrome). Once a person has AIDS, the risk of infection form almost anything can cause fatal complications.

HIV Virus Cycle

The menopause is that period in a woman’s life when her periods stop permanently. It’s a natural process that marks the end of a females reproductive years and the average age at which this happens is 51, although it varies from woman to woman. The menopause actually takes place when there aren’t any more eggs in the ovaries. It is these eggs that stimulate the production of estrogen, but when the levels of this hormone drop in the blood, the menstrual cycle is disrupted.

Menopause

The menopause normally takes place gradually and for a few years prior to it a woman’s periods may become more irregular; occurring every couple of weeks or every few months. Bleeding may be a bit heavier during this time as well.

Some women do not suffer any symptoms on the onset of the menopause, but approximately eight out of ten women do. These symptoms can include hot flashes, night sweats, mood swings, palpitations, insomnia, dry skin, thinning hair, brittle nails, aches and pains, loss of libido, headaches, weight gain, and vaginal and urinary changes.

The lower levels of hormones brought on by the menopause can also increase the risks associated with other health issues in the long term, including osteoporosis, heart disease, stroke, weight gain and weakness of the pelvis and pelvic floor.

Physical exercise and changes in diet can help in the treatments of the menopause, as does hormone replacement therapy (HRT), which is designed to replace some of the hormones after the menopause occurs.
