A uric acid level of 7 mg/dL is borderline and generally not a cause for concern, nor is it likely the cause of your fatigue or gas. To boost your energy and improve digestion, prioritize hydration, as water helps flush uric acid and aids bowel movements. For gas relief, you may try a daily probiotic supplement. Focus on a balanced diet low in high-purine foods (like red meat) and processed sugars, and include light daily exercise to naturally improve energy. Since your other reports are normal, there is no need to panic. Please consult a doctor before starting any specific uric acid-lowering medications.

Mild knee pain with crackling sounds and discomfort while climbing stairs for several years, with normal rheumatoid arthritis and gout tests, is commonly due to early osteoarthritis, cartilage wear, patellofemoral syndrome, or muscle weakness around the knees. Doctors may advise supplements such as Glucosamine, Chondroitin, Calcium, or vitamin D if deficiency is present. Physiotherapy, quadriceps-strengthening exercises, weight control, avoiding squatting/stairs overload, and regular low-impact exercise are very important for long-term relief. Pain relievers may be used occasionally if medically suitable. Please consult an orthopedic doctor or physiotherapist if pain worsens, swelling develops, or walking becomes difficult.

It is very common for joint pain to return when you stop taking your medication to control uric acid. Febutaz (febuxostat) helps keep your uric acid levels stable, but restarting it suddenly during an active flare can sometimes make the pain worse. I gently advise against restarting it on your own. Please consult your doctor so they can evaluate your knee and safely guide you on restarting febuxostat, possibly alongside a temporary pain reliever to make you comfortable.

Since your X-rays were normal and physical therapy hasn't brought relief, the next best step is to consult a podiatrist or orthopedic specialist. They may recommend an MRI or ultrasound to evaluate the soft tissues, like nerves or tendons, which do not show up on standard X-rays. Additionally, it would be wise to review your febuxostat treatment and uric acid levels with your doctor to ensure gout is fully controlled. In the meantime, try using supportive footwear or custom orthotics to relieve pressure on the area.
