It sounds like you may be experiencing sensitivity or irritation in your mouth triggered by sour foods, which can make chewing uncomfortable.

🩺 Possible Reasons

• Mouth sores or ulcers that sour foods irritate.
• Dental issues like cavities or gum inflammation worsened by acidic foods.
• Sensitivity due to enamel erosion or exposed dentin.

🏥 What You Can Do Now

• Avoid sour and acidic foods temporarily to prevent further irritation.
• Rinse your mouth with warm salt water to soothe any inflammation.
• Maintain good oral hygiene but be gentle around sensitive areas.

⚠️ When to See a Doctor

• If pain or inability to chew persists beyond a few days.
• If you notice swelling, bleeding, or worsening symptoms.
• If you have fever or signs of infection.

Consult a dentist for a thorough oral examination to identify the exact cause and get appropriate treatment. If you have other symptoms or concerns, a consultation with a general physician may also help.
