This in turn is most commonly caused by Diabetes Mellitus, Hypertension, Smoking or excess alcohol consumption. In some cases, vitamin B 12 deficiencies may also cause this kind of symptoms. If you were my patient, I would recheck your BP, fasting blood sugar, do some blood tests to know vitamin deficiencies and make necessary changes in Chat Doctor. Take Care! </s>
