Cat scratching over eyes and ears until its raw and bleeds

[u/juicy_spoots]

I dont know what to do anymore. We've taken her to the vet. They did bloodwork and said they found nothing. Gave her a shot to prevent infection. Shes 15yo tabby. It has been literal months of this hell. We have 2 donuts to swap out for her but if she gets them off she immediately destroys her face. It's awful and as it's my gf's cat it really upsetting her. I'm not sure what to do at this point. Their overall answer was Maybe alergies. We have removed new furniture. Swapped bad to old food she's been good on even bought a new litter box. They gave the flea treatment they put on the back of the neck. We have force fed seteroids to help with the issue but we cannot find a resolution. The only 2 major changes is my gf moved in with a friend and they have 3 animals but she was there about 8 months before any of this started and the food. We started feeding her wet food and the lickem gogurt things. GF even swapped laundry detergent to something for sensitive skin. The kitty is never around the other animals and only in the gfs room. Shes old and likes her space. The vet said possibly food allergy but its like $100 for a small bag and given it's a guess I'm really not sure what else to do here. has anyone experienced this before and can possibly help? I'm already out 2k trying to figure this out only to get a guess. Any advice would be greatly appreciated.

Thanks.

Could it just be anxiety? She's older and in a new type of environment so I would consider it at least. Our cat lost his sister pretty dramatically and afterwards he started chewing and scratching at a spot on his back between his shoulder blades until it was a raw wound. He wore a shirt to cover it for about a year and a half before he was able to go naked again. We haven't had problems since. We probably would have tried medication but he's a big orange stubborn boy and it takes three of us to get maybe half doses in him so we had to get creative. I know they sell diffusers and thunder shirts for anxiety.
