Depending on the severity of injury a may be simple overstretch muscle or tendon it can partial complete tear.?

Depending on the severity of the injury, a muscle or tendon strain can be:

- Simple overstretch: This is the mildest type of strain, and it occurs when the muscle or tendon is stretched beyond its normal range of motion. This can cause pain, swelling, and tenderness, but it usually does not require medical treatment.

- Partial tear: This type of strain occurs when some of the fibers in the muscle or tendon are torn. This can cause more pain, swelling, and tenderness than a simple overstretch, and it may require medical treatment.

- Complete tear: This is the most severe type of strain, and it occurs when all of the fibers in the muscle or tendon are torn. This can cause significant pain, swelling, and tenderness, and it will require medical treatment.

The treatment for a muscle or tendon strain will depend on the severity of the injury. Simple overstretches can usually be treated with rest, ice, compression, and elevation (RICE). Partial and complete tears may require more intensive treatment, such as physical therapy, medication, or surgery.
