An elevated uric acid level of 8.3 mg/dL indicates hyperuricemia, but it may not be the direct cause of your palm pain, which sounds more like a positional or nerve-compression issue (such as carpal tunnel syndrome). For temporary pain relief, you can use over-the-counter anti-inflammatory medications like ibuprofen or naproxen, and try gently stretching your hand. Please avoid taking long-term uric acid-lowering medications (like allopurinol) without a proper medical evaluation. I highly recommend consulting your doctor to determine if your high uric acid requires treatment and to get an accurate diagnosis for your palm pain.
