Waking up with foot pain is likely to be gout, as this form of attack is consistent with the characteristics of gout. Gout attacks are characterized by sudden onset of redness, swelling, pain and tenderness in a single joint, accompanied by an increase in local skin temperature, and the first joint is often the medial side of the big toe joint, so the nature of waking up with foot pain is very consistent with the characteristics of gout attacks. If you want to make a definite diagnosis, you can have a blood test for uric acid. If the blood uric acid level is >420μmol/L, the diagnosis of gout is usually clear. At this time, you can take oral colchicine for anti-inflammatory and pain relief to quickly stop the pain, and when the pain is relieved, you need to take continuous uric acid-lowering medication, and you can take oral febuxostat for uric acid-lowering treatment.
