Yes. When Hollows attack others, their own reiatsu goes into their prey, as a way of weakening and marking them. However, when injured, Hollows use reishi to regenerate. They try to take in whatever is around them, but because we're both shinigami and Hollow, it doesn't quite work. The shinigami side won't allow for the reishi of a Hollow to be absorbed.

It's a bit worse in your case, because your Hollow is so strong, that pull is even stronger. Plus if the only source available is the very arrancar that injured you, then it really makes it harder for you to heal. Understand?
