Hello. i've had constant numb/tingle in left fingers for 5 days, occassionally in left ear, & right now heat in left torso/arm.

Various symptoms: The left hand symptoms may be caused by nerve impingement in the wrist(-carpal tunnel syndrome), but symptoms in the ears and torso would be unrelated. If these varied symptoms persist, I recommend an evaluation by a neurologist who will order appropriate tests including checking for deficiencies of calcium, magnesium, potassium, vitamin b12,iron as well as for anemia and thyroid disorders.
