Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain numbness of tongue and mouth can occur due to causes that can also commonly cause numbness of tongue and mouth are
Vitamin B12 and
calcium deficiency,
potassium deficiency, traumatic injury or inflammation of branches of
trigeminal nerve that supplies the face,anxiety and panic attacks,
nerve inflammation and infection caused by viruses etc..
I would suggest you to consult a Neurophysician and get evaluated and can be advised to get investigations done like MRI, CT Scan, Nerve conduction studies, Electromyogram etc to rule out the exact cause of the problem and treat you accordingly..
You can be advised to take multivitamins along with calcium and potassium supplements..
You can do warm compresses over the lips.
You can also do breathing exercises along with meditation to keep stress minimal..
Hope this information helps..
Thanks and regards.
