Since paracetamol is not relieving your radiating pain, your next step should be to consult your doctor or an orthopedist. This pain is likely due to nerve compression from the cervical misalignment, which your doctor may want to evaluate further with an MRI. You can discuss alternative medication options, such as nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, or nerve-specific pain medications like gabapentin. Non-pharmacological treatments like physical therapy or a temporary neck collar might also provide relief. Please avoid heavy lifting, and seek prompt care if you experience worsening weakness or numbness in your arm.
