The rabbit grimace scale is difficult to interpret, especially so if you dont have some sort of baseline.
(For other readers: The rabbit grimace scale is used to asses pain/discomfort/distress in rabbits. Here is a picture of cheek flattening: 
It is very difficult to say if your bun has cheek flattening without knowing if there is a change from her normal look.
I dont think the grimace scale is very useful on its own, i e as an only measure of a bun’s comfort level. Changes in appetite, alertness, interest in the environment, poop (quality, size, amount, color and shape of poop), water consumption, hay consumption and body stance are also important to look at. One thing that is often a very visible clue as to how a rabbit feels is how the fur looks. (Although this is not always applicable if the bun is already in a big molt. Stress will however result in some shedding.)
How do the scabs look? Is there any redness, swelling, seepage? Does she seem bothered (excessive grooming of the area).
I think it would be wise for all us bun owners to take pictures of our rabbits when they are happy and relaxed, so we have a baseline for comparison. Although the grimace scale would still be very difficult to use with very fluffy rabbits.
