I am Dr Ravinder Sharma ENT surgeon. On the basis of the information provided it appears you have skin allergy
to metallic earrings. This time it appears you had a secondary infection too. Your medical history is suggestive of the autoimmune disorders
. They also predispose you for recurrent infections.
This interpretation is based on the information provided and it cannot replace a clinical examination by a ENT and Skin specialist. I would suggest you for a appointment with Otolaryhgologist and Dermatologist
It appears that you will need antibiotic (topical antibiotic
ointment), antiallergics and may be some steroid preparation for treatment. You may also require systemic antibiotics and antiallergics.I can understand your inability to attend a clinic because of twin toddlers but still this will be the right thing to do.
It would not advise you to use antibiotic ear drop
I hope this answers your concerns. Feel free to contact me if you need more information about it
