This pain often stems from deep muscle strain or core imbalances after changing your workout routine. Since standard oral painkillers and topical sprays only provide temporary relief, your doctor might consider prescribing a muscle relaxant (such as baclofen or tizanidine) if muscle spasms are present. For nerve-related discomfort, medications like pregabalin may be evaluated. Alternatively, a medicated lidocaine patch can offer targeted, continuous local relief. Please consult your prescribing physician to safely adjust your treatment. In the meantime, temporarily pausing strenuous core exercises and focusing on gentle stretching will support your recovery. Rest assured, this is a common and highly manageable workout-related issue.
