Hello Doctor,
I have been having sort of burning sensation of my upper and lower lips ( outer portion ) not inner portions, my tip of the tongue too feels a bit itchy ! I have never had this problem, I am 39 years old and have been on hypertensive medicine for the last 10 years ( recently around 9 months back) changed to losartan ( one in the morning and one in the evening after food ) does this have anything to do with this, or is my magnesium or calcium low ??? I quite puzzled so could please let me know whats the problem or what tests i need to take to check this problem, thanks for all the answers. Ponyguy
