###Human: What causes boils in the ear of a diabetic and hypertensive patient? ###Assistant: Hello. With the picture it appears like a hair follicle infection of the small hair in the ear canal (attachment removed to protect patient identity). Considering her age and that she suffers from diabates and hypertension (diabetic people have slightly less immunity compared to normal people) I am suggesting antibiotics for her. Tablet Augmentin 625, 1 tablet thrice daily after meals x 5 days, tablet Chymoral Forte 1 tab thrice daily before meals x 3 days, tablet DOLO 650, 1 tablet SOS for pain, can take upto three tablets per day in divided doses. T-BACT ointment use clean little finger and apply the ointment thrice daily over the area. If using ear buds take particular care that it does not go deep and injure the ear drum. Do not let water enter while taking bath. Keep a cotton plug (spread with some T-Bact ointment or vaseline) inside the affected ear and throw it off after bath. This condition is called acute localised otitis externa (furuncle of external ear). It appears that there is a single boil with a lot of redness in the picture you showed. It is quite painful. Please continue your diabetic and hypertension medicines as before. I hope you are taking those regularly and the sugars are controlled. For a few days avoid applying oil in hairs. Once she gets better, she can put oil over scalp. Do revert back if there is any worsening. Please wait for 3 days for the antibiotics and medicines to act. Please let us know promptly if there is any fever or some other form of worsening. Happy to help you.
