I have a small wound in my armpit. kinda like a blister that popped, the size of a bead. but its over three weeks now and won't heal, occasionally a little pus comes out and stings when in contact with water. how to heal this?
The biggest thing you can do is keep the area clean and try to keep it dry. Wash with soap and water and place some antibiotic ointment on it. If it doesn't heal up soon, you may want to head to the doctor to see if the infection is more serious and needs addressed other ways.
