I am newly diagnosed diabetes type 2 the doctor prescribed these tablets for me I take one in the morning and one at night. The thing is since I started taking them two weeks back I have terrible side effects such as : chill with fever, a headache, every single part of my body hurts, and I have as diarrhea and as for the diet I eat what is available for me because I'm currently unemployed 
Should I be worried about these side effects or they are normal and perhaps they will go away on their own?
