I am recently feeling pricking in my fingers of both legs, pain in my calf muscle of left leg and sometimes a burning sensation in under- feet. My sugar levels are 110 to 120 fasting and 160 to 180 pp. My b p levels are mostly a little over 120 (125-130) and a little less than 80 (70-75). I was prescribed glinil m for sugar management and no medicine for bp management. Blood test results are :urea serum - 22 mg/dl, creatinine serum-0.9 mg/dl, sodium serum-141mmol/l and potassium - 5.0mmol/l. I am 68 years old. Please suggest me what is the health condition by my above symptoms and what steps do I need to adhere to manage the condition and what precautions, if any, should I take.
