What could be causing my 55-year-old aunt?s painful and swollen left foot if it is not improving with her usual medicines, FURIC-40 and Nucoxia-90, especially since her uric acid levels are normal this time and she also takes medication for high blood sugar, high blood pressure, and an underactive thyroid, based on her attached thyroid and cholesterol test results?
Since FURIC-40 (febuxostat) and Nucoxia-90 (etoricoxib) are not providing relief, and her uric acid is normal, other factors may be at play. In patients with diabetes and thyroid conditions, a swollen, painful foot could stem from a localized infection, a different type of arthritis like pseudogout, or a diabetic bone and joint issue called Charcot foot. Interestingly, uric acid levels can sometimes drop to normal during active gout flares. I gently recommend having her doctor examine her foot and perhaps perform an X-ray to safely find the exact cause.
