Hi, thanks for the query to H.C.M. Forum.
The pain in throat , around the ears, recurrent pain, relief from antibiotics are suggestive of,
Asthmatic allergic bronchitis
( precursor of asthma)
are common features of all above mentioned conditions.
You are responding to antibiotics means a low grade infection due to allergy.
Confusion as you mentioned in your query is due to all above conditions.
So please avoid these conditions and don't use antibiotics as this will produces resistance.
Still there is no improvement than consult a physician and have a proper treatment.
Thanks Dr. HET
