hi there, your symptoms are suggestive of condition other than gout
and you need further investigatyion. You are saying that there was numbness
few days back followed by swelling of the knee and warmth of the extremity,these all are suggestive of an infective etiology and you will need to see if you have any injury
on your foot or leg in which case you might need to get it examined by a doctor. Also a deep vein thrombosis
cannot be ruled out and so getting a colour doppler done for the lower extremety would be quite informative. Also moniter your blood sugar level and get an endocrinologists help to keep it under control. It is not a light matter and it would be a good idea to get a thorough exam done before you leave it to be gout and further management need to be done . Take care.
