Hello, I ve had tingling and sharp pains in my feet that started over a year ago and have gotten worse with time. They started in my right foot and now i occasionally get them in my left foot. My hands and feet also fall asleep frequently, occasionally just when they are extended or with light pressure, or no pressure on them at all. I ve seen a neurologist and there is no issue with my nerves. I have also had chronic stomach issues for which I ll be making a GI appointment soon. Do I need to be concerned about cardiovascular issues with the numbness and tingling? Thank you, Natalia
