S33.9

Clinical Causes: Sudden twisting or excessive movement of the lower back or pelvis Falls onto the lower back or pelvis Car or sports accidents causing impact to the lumbar or pelvic region Lifting heavy objects improperly Repetitive strain or overuse of lower back muscles Poor posture that puts undue stress on the lumbar spine or pelvis

Key Symptoms: Localized pain in the lower back or pelvic region Muscle stiffness and tenderness Swelling and inflammation in the affected area Limited range of motion or difficulty moving in certain directions Muscle spasms or cramping Possible radiating pain into the buttocks or upper thighs

Diagnosis Path: Diagnosis typically involves a comprehensive medical history assessment and physical examination to evaluate pain points, range of motion, and areas of tenderness. Imaging tests such as X-rays may be used to rule out fractures or structural damage, though ligament sprains often do not show up clearly on radiographs. In some cases, MRI scans are considered to assess soft tissue damage more precisely. The healthcare provider may also perform neurological assessments if nerve involvement is suspected.

Treatment Protocols: Rest and avoiding activities that exacerbate pain Application of ice packs during the initial 48 hours to reduce swelling Use of over-the-counter pain relievers such as acetaminophen or NSAIDs Physical therapy to strengthen supporting muscles and improve flexibility Gentle stretching exercises as recommended by a healthcare professional In some cases, a brace or support belt may be advised to stabilize the area Gradual return to normal activities as pain subsides Avoiding heavy lifting and strenuous activity during the recovery period
