Hello
Welcome to health care magic.
The numb spot below and around your lip doesnot seem to be because of anything in your brain.
It can be because of hypoglycaemia/hypocalcemia/sign of impending shingles/allergy to certain food,medications,chemicals.
If you suspect any recent exposure to certain food esp sea food or chemical/medications with experiencing of these symptoms you may take oral
cetrizine,anti histaminic once aday for 3 days.
Besides,as the numb spot has been present for more than 10 days, advice certain investigations like fasting blood glucose,serum calcium levels.
Lowering of calcium levels are also associated with muscle ache,muscle spasm and
fatigue.Do you have such symptoms?
You also need to look for and report immediately if the area of
numbness increases with headache,or if you have
muscle weakness,vision problems.This signifies impending stroke.
Look for appearance of any red
blister over the area or development of redness and warmth in the area signifying shingles.
Hope this information helps.
Feel free to ask any more doubt.
