Check up needed: BLUEISH tinge to the tongue may be due to prominent venous pattern and is unlikely to be significant. I recommend a complete check up by your physician including tests to look for anemia, iron deficiency, underactive thyroid,low blood pressure, abnormally slow heart rate, as well as electrolyte abnormalities and any signs of infection or depression.
