Since Voveran SR (diclofenac) and Myotop (tolperisone) are not relieving your severe, sharp pain after a bike accident, you require a proper physical evaluation rather than just switching medications. This persistent pain could indicate a structural injury like a shoulder dislocation, rotator cuff tear, or fracture that oral painkillers alone cannot fix. Please consult an orthopaedic specialist immediately for an X-ray or MRI. In the meantime, immobilise your arm using a shoulder sling, apply ice packs for 15 minutes to reduce swelling, and avoid movement. Your doctor may prescribe stronger prescription analgesics, such as a tramadol-paracetamol combination, once a definitive diagnosis is made.
