6 months post-op, what can I do about painful raised red scarring? (Photos)

I’m 6 months out and my scars are very red and raised. They started to look worse as opposed to better around 3 months. I don’t have itching but experience sharp short pain in them sometimes. I’ve spoke only to the nurse at my surgeons office and was recommended MEPITAC tape, should I be doing anything else are these keloid or going to get worse?
