The only way to know for sure what's causing the bumps on your cat's head is to take your cat to the vet. The vet will be able to examine the bumps and recommend the best course of treatment.
In the meantime, here are a few things you can do to help your cat:
* Keep the bumps clean and dry. Gently cleanse the bumps with warm water and mild soap, and then pat them dry.
* Apply a cold compress to the bumps. This can help to reduce inflammation and swelling.
* Give your cat pain medication if necessary. If your cat is in pain, you can give them over-the-counter pain medication, such as aspirin or ibuprofen. However, be sure to talk to your vet before giving your cat any medication.
* Monitor the bumps closely. If the bumps change in size, shape, or color, or if your cat starts to show other symptoms, such as lethargy, vomiting, or diarrhea, take your cat to the vet right away.
