If your body pain persists despite taking PCM 650 Tablet (Paracetamol), it may indicate an underlying condition such as muscle strain, a viral infection, or inflammation. You can try supportive measures, such as gentle stretching, applying heat or cold packs to sore areas, and staying well-hydrated. If the pain continues, worsens, or is accompanied by other unusual symptoms, consult your doctor for further evaluation and treatment.
