For patients with posterior thigh strains, the main cause is myofascial edema, which can lead to pain and limited movement of the posterior thigh. Therefore, within 24 hours after the strain, cold compresses must be applied to the strained area, and the activity and weight-bearing of the thigh should be restricted to create conditions for the repair of the strained tissue. After 24 hours, we can apply blood-stasis activating drugs and oral treatment to promote the edema of strained tissues and tissue recovery. 48 hours later, we can apply hot compress on the back of the thigh to promote local blood circulation and promote the swelling and recovery of strained tissues. Generally, excessive weight-bearing activities and walking should be avoided within two weeks after the strain to avoid poor recovery of the strained tissues.
