Hello
Welcome to health care magic.
I have gone through your question very diligently and I really appreciate your concern.
Tingling sensation in hand and feet might be related to
high blood pressure, thromboangitans obliterans ( more prevalent in smokers),
Hypocalcemia,
hypothyroidism and many other causes.
I would advise you to keep a record of blood pressure and make a chart, please upload me the chart for further clarification.
I would advise you for a battery of investigation like CBC, ESR, blood sugar, Liver function test, serum calcium and vitamin D estimation test, thyroid function test, kidney function test and urine microscopy.
Meanwhile I would advise you to take
multivitamin supplement and calcium daily for 10-15 days.
Hope you will find my answer informative and useful, please feel free to ask for follow up question I will gladly answer you.
Best wishes
