Please do not continue taking Arflur 3D (a pain reliever) without consulting your doctor, as long-term use can cause stomach or kidney issues. While Mecobion and 2b12 support nerve health, the pain returning with continuous work suggests an underlying issue like muscle strain, poor posture, or nerve compression. I recommend stopping the painkiller and visiting your doctor for a proper evaluation. You may need ergonomic adjustments at work, physical therapy, or further diagnostic tests to address the root cause of the pain rather than just masking the symptoms.
