Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain mild pain in ear radiating to area around eae and jaw and a soft lump behind the ear are all indicative of
Ear infection and the lump seems to be swollen post auricular
lymph node secondary to infection..
In case if it is not due to infection causing inflamed lymph nodes the other causes can be
lipoma or a sebaceous cyst and both are harmless..
You should consult an Otolaryngologist and get evaluated and an Otoscopic examination can help in confirming the cause and treatment can be planned accordingly..
In case of infection antibiotics Oral as well as ear drops,anti-inflammatory painkillers like
Ibuprofen and warm compresses around ear will relieve..
As of now you can take
Tylenol or Ibuprofen for relief..
Hope this information helps..
Thanks and regards..
