Thanks for your query,
It seems you are suffering from parotitis
which presents as large painful lump on the sides of ear.Apart from the efforts you are making, you may also need a antibiotic like amoxycillin
or other as well as some anti inflammatory drugs, depending upon the severity. I suggest you to consult a ENT specialist
for proper initiation of tratment after proper examination and confirmation.
Take care and best of luck..
Hope it helps..
