<s>[INST] Hi there, I am 33 overweight female with high blood pressure, have suddenly developed tingling feet and hands while lying in bed and having weird head spins. Am on blood pressure medication and currently on weightwatchers losing an average of 1 kilo a week. Should I be concerned about tingling in hands and feet [/INST] Hello, 2 things I would like to recommend.  1) Keep a tab on blood pressure if you have a machine at home . Make sure that the blood pressure is well under control with medication . A slight variation in comparison to normal self may result in all symptoms you describe.  2) see which medication you are taking for reducing weight . Most of they have a lot of side effects which include an increase in blood pressure which may cause headache and tingling . An exact information on the medication will help me be more objective . However if your blood pressure is normal and yet you are having symptoms ,  Stop the weight watcher medication . Hoping I could help . Regards Dr. Priyank Mody </s>
