Leg swelling with pain, along with high uric acid and raised creatinine, can suggest strain on the kidneys, along with possible gout-related inflammation. Keep taking your prescribed medicines regularly and avoid stopping them on your own. Drink enough water unless your doctor has restricted fluids, so the body can clear waste more effectively. Follow a simple diet with less salt, red meat, alcohol, and heavy foods to reduce the load on the kidneys, and keep your leg slightly elevated at rest to reduce swelling. Avoid overexertion and monitor your urine pattern and general energy levels. If swelling increases, pain becomes severe, or weakness worsens, consult a kidney specialist soon for a detailed evaluation and proper guidance.
