Hi. I got home from work Sunday and my cat was limping. When checking her paw I see a blister like injury on her toe. I took her to the vet Monday and they really didn’t look at anything, because “it seems to bother her.” Very unhelpful lol. I sent them a photo and they gave me gabapentin and an antibacterial cream. I know it’s only been a day but she’s still in pain and I feel like it’s looking worse.

Does anyone know what this is? Should I soak her paw in salt water to help soothe it? Any advice is greatly appreciated! First pic was yesterday, below is today.
