Ligaments are strong bands of tissue that attach one bone to another. The cruciate (KROO-she-ate) ligaments connect the thighbone (femur) to the shinbone (tibia). The anterior and posterior cruciate ligaments form an "X" in the center of the knee.

Although a posterior cruciate ligament injury generally causes less pain, disability and knee instability than does an ACL tear, it can still sideline you for several weeks or months.

Migraines, which affect children and teenagers as well as adults, can progress through four stages: prodrome, aura, attack and post-drome. Not everyone who has migraines goes through all stages

What is backache?
Backache is one of the most common medical complaints, particularly among adults. Backache usually refers to pain in your muscles, intervertebral joints, spinal nerves, or sometimes bone-on-bone pain. The type of pain you are having can help your physician pinpoint the cause.
Backache can be categorized as acute or chronic. Acute pain is often temporary and can improve on its own, frequently without treatment or with the assistance of a mild pain relieving medication. Acute backache usually lasts anywhere from a couple of days to several weeks. Chronic back pain is more long-term and can extend beyond several months. The pain can often be progressive, getting worse over time.
Once your medical practitioner determines the cause of the pain, there are usually appropriate treatments either to relieve the symptoms or to eliminate the pain source altogether. With appropriate treatment, your backache can often be resolved or managed with strategies that enable you to resume most of your normal activities.

It’s known as a calcium crystal disease because the pain is caused by crystals of the mineral calcium rubbing against soft tissue.

It most commonly affects the knees, but can affect other joints too.

Calcium crystals are normally in bones and teeth to help make them strong. However, people can have too much of these crystals and in the wrong place in the body, and this can cause problems.

Many people can have calcium crystals in their cartilage for years without them causing any problems.

However, these crystals can move from their protected site within the cartilage into the space between the bones in a joint. This area is called the joint cavity. This can cause pain and swelling as the sharp, hard crystals rub against soft tissue.

The process of the crystals shaking loose and leaving the cartilage is called crystal shedding.

The name of the condition comes from the substance which forms into crystals, calcium pyrophosphate.

An old name for acute CPP crystal arthritis is pseudo-gout, or false gout, because the symptoms look like a condition called gout. However, gout is caused by crystals of the waste product urate rather than calcium crystals.

It’s rare for acute CPP crystal arthritis to affect people under the age of 60.

-Neck pain is pain in or around the spine beneath your head, known as the cervical spine. Neck pain is a common symptom of many different injuries and medical conditions.
-You might have axial neck pain (felt mostly in the neck) or radicular neck pain (pain shoots into other areas such as the shoulders or arms). It can be acute (lasting from days to up to 6 weeks) or chronic (lasts longer than 3 months to years).

-Neck pain can interfere with daily activities and reduce your quality of life if left untreated.

Cancer is a disease where cells in the body replicate abnormally and form a mass known as a tumour. These abnormal cells multiply, either causing the tumour to grow or the cancerous cells to spread through the bloodstream.

Here are some common cancer symptoms to look out for:

Smoking is one of the leading causes of cancer. If you are a smoker, there is no time like the present to quit smoking.

Thanks to medical research, cancer survival rates have been steadily improving for decades. Sadly, the survival rate is generally lower for older people. Therefore, it’s very important to catch symptoms early and begin treatment as soon as possible.

Bone pain, tenderness, or achiness is a common problem, particularly among those who are middle-aged or older. As you age, your body undergoes many changes. Muscle size and bone density generally decrease as you become less active. This makes you more prone to overuse injury and bone fractures.

While bone pain is most likely due to decreased bone density or an injury to your bone, it can also be a sign of a serious underlying medical condition. Bone pain or tenderness could be the result of infection, an interruption in the blood supply, or cancer.

If you have an ear infection, fever and temporary hearing loss may occur. Young children who have ear infections tend to be fussy and irritable. They may also tug or rub their ears.

The most common things people who become ill with COVID-19 have include:

These symptoms can start anywhere from 2 to 14 days after you’re in contact with the virus.
