Muscle Strains and Tears
Muscle strains can also be referred to as a muscle pull, a muscle tear, or a complete rupture, which refers to damage to muscle fibres or its attaching tendons. Muscle tears are graded between Grade 1 to 3, Grade 3 being the most severe.
Undue pressure can be put upon the muscle by one sudden movement, or a minor strain, which has progressively got worse by being left untreated. For example; during normal daily activities, sudden heavy lifting, overstretching during sports, or a sudden impact.
The tearing of the muscle causes damage to the small blood vessels causing local bleeding, or bruising, and pain caused by irritation of the nerve endings in the area.
