hi, thank-you for providing the brief history of you. A thorough neuromuscular assessment and musculoskeletal assessment is advised. As you have pain in the lateral side of the left lower limb it can be due to two factors. Either due to a nerve pinch in the spine as this may lead to abnormal sensory and motor changes in its course and second may be due to muscle weakness leading to fatigue in muscles and pain. Understanding the proper cause by a clinical assessment and if required an MRI will help suggest the possible issue. Also, undergoing physical therapy like therapeutic ultrasound therapy and TENS therapy will help reduce pain and inflammation. Performing exercises post this will help make the muscles stronger and hold the joint in place to reduce the stress and strain. in my clinical practice such cases respond well to physical therapy and near normal recovery is achieved.
