Why does my cat keep getting worsening cuts and blisters on her ears?

Question

In the past month my cat has developed blister/cuts on her ears right after the other would heal. One of them just healed and a third one appeared right below it. Everytime the cuts seem to get worse and I'm not sure if she's hurting herself on accident when itching her ears or if it's something else. I have a picture of her ears below. The new blister is on the bottom left and the white spot above it is her previous healed one. Pet's info: Cat | Domestic Shorthair | Female | spayed | 6 years and 7 months old | 12 lbs

This presentation could be due to a trauma (autotraumatism) or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any scratching.
