My husband is diabetic. his blood sugar has been running very high for the last few days...158 to 196..also his feet and ankles have been swelling and his right knee is painful and a little swollen.  I took him to see his Dr. when it first started...she thought it would be ok.
Hi, If 158-196 mg/DL are fasting blood sugar results, than it is true that these are not good result. If these results are not fasting, than we can say that the situation of Diabetes is Ok! About her swelling in his extremities, there are several possible causes like heart disease, kidney disease, lymphedema, deep vein thrombosis etc. The pain and swelling in his right knee can be signs of a possible local inflammation and this can be the cause of her actual high blood sugars. My advice is to consult physically his doctor because it is necessary to do some blood tests and an X-ray of his right knee to check for possible causes that can explain his actual situation. These tests are very important to reach the right diagnosis. A diuretic scan be helpful but only after the right diagnosis you can have the right treatment. Hope I have answered your query. Let me know if I can assist you further.
