Strain Severity: Strains are categorized in a similar manner to sprains:
* Grade I Strain: This is a mild strain and only some muscle fibers have been damaged. Healing occurs within two to three weeks.
* Grade II Strain: This is a moderate strain with more extensive damage to muscle fibers, but the muscle is not completely ruptured. Healing occurs within three to six weeks.
* Grade III Strain: This is a severe injury with a complete rupture of a muscle. This typically requires a surgical repair of the muscle; the healing period can be up to three months.
