-Soft tissue sarcomas
Soft tissue sarcomas are a group of cancers that grow in parts of your body such as your muscles, bones, deep layers of skin, or in fat. They also can form on blood vessels, nerves, or connective tissues, which support organs and other kinds of tissues.
Soft tissue sarcomas are rare. They account for less than 1% of all cases of cancer. But there are dozens of different types, and they can happen in children and adults.
About 13,000 people are diagnosed with one of these cancers every year.
Symptoms
The most common sign of a soft tissue sarcoma is a painless lump or growth. But some may not be noticeable until they’re big enough to press on nearby muscles or nerves.
About 1 in 5 soft tissue sarcomas happen in the belly. You probably wouldn’t learn that you have one until they caused other problems, such as stomach pain, bleeding, or a blocked intestine. A doctor might find a sarcoma in your lungs or chest only after you have chest pain or trouble breathing.
-Sprain
A sprain is a stretching or tearing of ligaments — the tough bands of fibrous tissue that connect two bones together in your joints. The most common location for a sprain is in your ankle.
Symptoms
Signs and symptoms will vary, depending on the severity of the injury, and may include:
-Pain
-Swelling
-Bruising
-Limited ability to move the affected joint
-Hearing or feeling a "pop" in your joint at the time of injury
-Luxation
It is more severe injury that involves a change in the position of the joints and a bone separation.
Symptoms
-Pain.
-Swelling.
-Bruising.
-Instability of the joint.
-Loss of ability to move the joint.
-Visibly deformed joint (bone looks out of place)
-Strain
Muscle strain, muscle pull, or even a muscle tear refers to damage to a muscle or its attaching tendons. You can put undue pressure on muscles during the course of normal daily activities, with sudden heavy lifting, during sports, or while performing work tasks.
Muscle damage can be in the form of tearing (part or all) of the muscle fibers and the tendons attached to the muscle. The tearing of the muscle can also damage small blood vessels, causing local bleeding, or bruising, and pain caused by irritation of the nerve endings in the area.
