What Do Cramps In Muscles, Constipation And Sugar Being 252 Suggest?

Hi, my name is Sherry, age 51, about 5 3 and 148lbs. Since Super Bowl Sunday, I have been dealing with gut issues. Thought it was just constipation. On Wednesday, I felt better and went bowling. Before I could leave the bowling alley, I started having cramps in my muscles. I ended up with a 102.5 temp, blood sugar was 115. Felt pretty good next day. Today, I am having cramps in my stomach again. I checked my blood sugar and it is 252. Was 138 when I got up. I am not on meds. Any help would be appreciated. Thank You
