Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain it seems that while you rubbed your ear there has been traumatic
injury to the inside of ear and the bout of a
cold sensation running from ear down the jaw and cheek can be due to
nerve stimulation at the time of rubbing and leading to running of a sensation along the nerve route..
In case if you do not have any problem in ear after that and there has been no other episode of the same symptoms you need not to worry as there does not seems any damaging injury..
In case if you have a toothache you should consult an Oral Physician and get evaluated and along with a thorough clinical evaluation he can advise you antibiotics and painkillers and after taking an
x ray he can advise you appropriate treatment like
root canal treatment or extraction depending upon tooth condition..
Hope this information helps..
Thanks and regards.
