Hello. I m a 59 year old African American woman. I was recently diagnosed with Type 2 Diabetes. I was placed on Metformin (1000 mg) and Glipizide (5 mg). I have blurred vision and have developed these cramps in my legs. My toes twitch at night and all during the day I feel like I m getting ready to get a cramp in my left thigh joint or in my calves. It feels as though something is attacking my nerves. I have a tightening across my back out into my arms - both of them. I can t reach behind me to unfasten my bra because I begin to cramp up in my arms. Can you tell me whether I should seek a specialist? I don t know what kind to see. I m also on Triam/HCTZ for hypertension and edema. I take Vitamin D, B12, magnesium. Can you give some advice?
