Your symptoms are more suggestive of mechanical or posture-related lower-back pain than a direct complication of a C-section performed four years ago. Reduced abdominal/core and hip-muscle strength, prolonged unsupported sitting, and poor sitting posture may contribute. However, since the pain has increased over the past few months, an in-person examination is advisable to check the spine, sacroiliac joints, abdominal muscles and nerves.
Next Steps
Consult an orthopaedic doctor. Use proper lower-back support while sitting, keep both feet flat, and change position every 30–40 minutes. Gentle walking, local heat and supervised core, gluteal and pelvic-floor strengthening may help. Routine scans are usually unnecessary initially unless examination suggests nerve involvement, another underlying condition, or symptoms fail to improve.
Health Tips
Seek urgent medical attention if you develop pain radiating down the leg with progressive weakness, numbness around the genital area, loss of bladder or bowel control, fever, unexplained weight loss, severe night pain or pain following trauma
