For a number of weeks I have been experiencing tingling in my tongue and hands, mainly at night, during the day it seems to improve.  I have also had what I can only describe as a pulsating feeling in my lower abdomen.  I have no blood in my urine and no pain just an uncomfortable feeling.  Everything functioning as normal.  Have been to the doctor 3 times and no conclusion.  Had blood test for thyroid and mineral deficiency but all ok.  Cholesterol is slightly high and I wonder if this could be something to do with my problems.  I am not overweight and eat a healthy diet.
