Hi, Thanks for your question. After going through your question, there is likely possibility of retroauricular lymphdenopathy ( Lymph node swelling) most likely due to infection or infection of hair follicle. As you are not willing to go to doctor, you can try antibiotic like Amoxicillin+clavulunic acid along with pain killer and anti-inflammatory medicines for 5 days . If even after 5 days of treatment or if there is increase in size of swelling, high grade fever, swelling over other parts of the body there is a need for consultation with doctor for detailed clinical examination depending upon it further investigations may help in diagnosis and treatment. - Complete blood count. - ESR, CRP. - Chest xray. - Ultrasonography of swelling and abdomen. Hope this helps you, if so do vote as helpful.
