Hi, thanks for using healthcare magic
It is quite possible that you are allergic to the material the ear rings are made of. The only way to confirm this would be an allergy
test, this can be a blood test
or skin prick testing.
Alternatively ,if these tests are not an option, then change the type of earrings that you use. This can be done after this acute reaction has resolved.
The bumps are likely enlarged lymph
nodes that are responding to this acute event.
This present reaction can be treated with (1) removal of the earrings (2) application of mild steroid
and antibiotic cream (3) you can use an oral anti inflammatory pain killer to help with the sore throat
I hope this helps
