Gout is a type of arthritis caused by high levels of uric acid in the blood, which can form crystals in joints and cause pain. Since you have pain in your ankle and a high uric acid level (11.4), these could be signs of gout. Common symptoms include:

• Sudden, intense joint pain, often starting at night, frequently affecting the big toe but can involve the ankle or other joints.
• Swelling and redness around the affected joint.
• Warmth and tenderness in the joint area.
• Limited range of motion due to pain and swelling.

If you are experiencing these symptoms, it is important to see a rheumatologist or an orthopedic specialist for proper diagnosis and treatment. Managing uric acid levels and addressing inflammation can help relieve symptoms and prevent future attacks.
