Hi, I Have Been Diabetic For The Past Ten Years.

Hi, I have been diabetic for the past ten years. About a year ago my doctor
put me on Metroform, 1000 mg in the morning and another 1000mgs in the evening. I began to have diarreaha and getting real faint and my veins in my lower legs were popping wiith blood bloches below the skin not bledding, except one time breaking and my foot turned black. Flutering in my insides.
I stopped taking that medicine about 3 weeks ago after I visited my doctor and explained my condition. He then put me on Glipizide 2 five mg in the morning and 2 five mg in the evening.

I am still having some under the skin bleeding spots on my lower legs...
My regular doctor is on leave. What should I do? thanks.
