I'm sorry to hear about your neck pain and motion sickness while using your mobile phone. This is a common issue often related to poor posture and eye strain.

Here are some steps you can take to help prevent these symptoms:

• Maintain good posture: Keep your phone at eye level to avoid bending your neck forward. Sit upright with your back supported.
• Take frequent breaks: Follow the 20-20-20 rule—every 20 minutes, look at something 20 feet away for at least 20 seconds to reduce eye strain and motion sickness.
• Limit continuous phone use: Try to reduce the duration of continuous phone usage.
• Use anti-glare screen protectors: This can help reduce eye strain.
• Stay hydrated and ensure good lighting: Proper hydration and adequate lighting can reduce discomfort.
• Neck exercises and stretches: Gentle neck stretches can relieve muscle tension.

If motion sickness symptoms persist, medications like those containing dimenhydrinate (available as prescription-only tablets) may help, but you should consult a doctor before use.

Since your symptoms involve both neck pain and motion sickness, I recommend consulting an orthopedic specialist for your neck pain and a neurologist or ENT (ear, nose, and throat) specialist for motion sickness evaluation and management.

If symptoms worsen or you experience additional issues like dizziness, severe headache, or vision changes, seek medical attention promptly.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
