Left shoulder pain lasting 15 days with a normal X-ray could be due to soft tissue issues like muscle strain, tendon inflammation, or bursitis rather than bone problems.

🩺 Possible Causes

• Muscle strain or overuse without obvious injury
• Tendon inflammation (tendinitis) or bursitis around the shoulder joint
• Early signs of rotator cuff problems or referred pain from the neck

🏥 Management Steps

• Use over-the-counter pain relief such as NSAIDs (non-steroidal anti-inflammatory drugs) if suitable
• Apply ice or heat to reduce pain and inflammation
• Gentle shoulder stretching and avoiding heavy lifting or repetitive overhead activities

⚠️ When to See a Doctor

• If pain worsens or limits daily activities
• If you develop weakness, numbness, or swelling
• If pain persists beyond a few more weeks despite self-care

Since your X-ray is normal, consulting an orthopedic specialist or a physiotherapist would be helpful for a detailed evaluation and tailored treatment plan.
