Hi,
1. The most common cause for such
ear numbness or pain would be an odd position while sleeping or pressure on the ear
cartilage after sleeping in the same position for an extended period of time.
2. Other common causes would include:
a.
Ear wax build-up.
b. Ear infections including early
herpes zoster oticus (usually with a rash in the
ear canal).
c. Referred sensations from a large area of the head, neck and beyond (due to common nerve supply).
d. Nutritional deficiencies and so on.
3. It is important to get the ear examined if this happens often. Other wise it may be ignored. I must emphasize that a serous cause is unlikely.
I hope that I have answered your query. If you have any further questions, I will be available to answer them.
Regards,
Dr. Iven Romic Rommstein, General Surgeon
