Hello,
Welcome to icliniq.com.
I read your query and understood your concern.
I have reviewed the pictures you attached (attachments removed to protect the patient’s identity), it appears to be a hair follicle infection of the small hair in the ear canal. Considering her age and the fact that she suffers from diabetes and hypertension (diabetic individuals tend to have slightly lower immunity compared to non-diabetic individuals), I suggest she take antibiotics. I suggest she take a tablet containing Amoxicillin and Clavulanic acid 625 mg three times a day after meals for five days, a tablet containing Trypsin and Chymotrypsin three times a day before meals for three days, and a tablet Paracetamol 650 mg as needed for pain, with a maximum of three tablets per day in divided doses. For the affected area, I suggest she use an ointment containing Mupirocin IP 2.0 % w/w with a clean little finger, applying it thrice daily. If she use ear buds, be cautious not to insert them deeply and avoid injuring the ear drum. While bathing, ensure that water does not enter the ear. Insert a cotton plug into the affected ear after applying some ointment or Vaseline, and remove it after bathing. This condition is known as acute localized otitis externa (furuncle of the external ear). From the picture you provided, it seems to be a single boil with significant redness. It can be quite painful. I suggest she continue her regular diabetic and hypertension medications as prescribed. Ensure that she is taking them consistently and that her blood sugar levels are controlled. For a few days, I suggest she refrain from applying oil to her hair. Once her condition improves, she can resume applying oil to her scalp. If there is any worsening of the condition, you can reach out. Allow three days for the antibiotics and medications to take effect. I hope this has helped you. Kindly follow up if you have more doubts.
Thank you.
