Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it is true that swelling below the ear can be due to 2 main causes:
1. Wisdom tooth problems.
2.Infection or blockage in the
salivary gland, more specifically
Parotid gland that is a major salivary gland located in that area..
In case if there is no related dental issue ruled out, it is probably due to salivary gland..
At times infection in the salivary gland can cause swelling in the area infront and below the ear..
It can be treated well with antibiotics as you are given
Cephalexin..
In case if the duct the gland that carries saliva from the gland to mouth is blocked with foreign body or there can be formation of crystalline stones in the duct of the gland leading to resistence in the flow of saliva to the mouth and it accumulates in gland due to backflow..
In this case eating tart/sour candies, drinking plenty of water can at times remove the obstruction with heavy flow of saliva..
In case if it does not occur then either manual palpation of superficial stones can be remvoed by pushing them towards duct opening..
Deep located stones needs surgical removal..
In case if the swelling does not subside with antibiotics and it recurs, you should get an
x ray or
MRI scan of the gland done for ruling out stones and get treated accordingly..
Hope this information helps..
Thanks and regards.
