Mouth, tongue numbness, what medicine to take

Patient's question:

No

Doctor's answer:

If the elderly have numbness in their tongue, it should be considered whether there is a deficiency of qi and blood or high blood viscosity. Observing the tongue coating is only one aspect of diagnosis, and the symptoms shown by the tongue coating may also be false.
Special reminder: If you notice any abnormalities in your tongue, it is important to seek a diagnosis from a regular hospital in a timely manner. Please never draw conclusions or take medication on your own.
