I was given predisone twice in the last 6 months.Once for poison oak second time for inflammed muscles.My last run of predisone was probabaly 3 to 4 weeks ago.For the last week my blood sugar has averaged 355.Am I doomed to have high blood sugar from now on.I am eating strictly ,walking and it seemingly is not changing.Will this last.I take 1000 mg of metformin and 1 junuvia a day.Is there anything else I can do.
