I'm sorry to hear about your severe neck pain and difficulty moving. Neck pain with limited movement can be quite distressing.

Here are some steps you can try to relieve the pain:

• Rest and avoid sudden neck movements to prevent further strain.
• Apply a warm compress or heating pad to the neck area for 15-20 minutes several times a day to relax muscles.
• Gentle neck stretches and exercises may help once the acute pain reduces, but avoid forcing any movement.
• Maintain good posture, especially while sitting or using electronic devices.
• Over-the-counter pain relief such as non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. A medication combining an NSAID and a muscle relaxant is sometimes prescribed to relieve muscle spasms and stiffness.

Since your pain is severe and limits movement, it is important to consult an orthopedic specialist or a neurologist promptly. They can evaluate your condition thoroughly, rule out serious causes, and recommend appropriate treatment including medications like Etoshine MR Tablet (a combination of Etoricoxib and Thiocolchicoside) if suitable for you.

If you experience symptoms like numbness, weakness, fever, or worsening pain, seek emergency medical care immediately.
