A hamstring muscle contusion is due to a direct blow on the rear part of the thigh. This injury causes the muscle to be compressed against the bone.

This form of hamstring injury is common in contact sports. An impact or direct strike to the muscles can cause more damage than expected and should be treated properly. If the injury is not correctly managed or done in an aggressive manner, it results to myositis ossificans.
Indications of hamstring muscle contusion
The indications include pain at the site of the injury. In most cases, there is swelling, bruising and even limited movement.
An accurate diagnosis must be given since exercise while having a complete rupture or severe intramuscular injury can delay healing that can worsen the injury or lead to lasting damage. In case heat and massage is used during the initial phases, myositis ossificans can develop.
Management
A hamstring muscle contusion is categorized as grade 1, 2 or 3 depending on the extent of damage.
Grade 1
A grade 1 hamstring muscle contusion includes tightness in the rear part of the leg. The individual can walk but usually with a limp. There is minimal or no swelling and full range of motion is maintained.
The individual should rest and apply an ice pack right away for 10-15 minutes along with compression every hour during the initial 24-48 hours.
A sport injury professional can utilize sports massage and electrotherapy to hasten the recovery once the acute phase has passed. A rehabilitation program includes strengthening and stretching exercises to prevent injury in the future.
Grade 2
The individual can walk but have sudden pangs of pain during activity. There is minimal swelling and if the affected area is pressed, it is tender. Once the hamstring muscles are contracted against resistance, it triggers discomfort and there is marked limitation in movement.
Apply an ice pack and compression right away and avoid walking for 3-5 days. Sports massage and electrotherapy are beneficial in promoting the healing process.
Grade 3
The individual could not walk without using crutches. The individual experiences intense pain and evident swelling. During static contraction, it triggers pain and even a protuberance in the muscle. If the injury is severe, surgery might be recommended by the doctor.
