54 y.o. male w/ history of heart disease and type 2 diabetes. I beat an enlarged heart and type 2 diabetes at age 48 thru diet and exercise. In the last 6 months, old habits returned. Eating poorly and inactive. Started working out again about new year and eating better. Last night left side went numb suddenly, lasted about 20 minutes. Went away completely. Came back in the middle of the night. Gets stronger and weaker. If diabetes, not likely to be entire side of body. If stroke, not likely to go away and return. Varying degree of numbness also odd. Like the side, especially the arm, has fallen asleep. Sometimes very pronounced, sometimes, just slightly numb.
