Why does my moon cactus look like this? The stock is very hard,strong, & green. It looks like something is poking thru from the inside out. Its been like this for a few months now and I don't know why. Thank you

It looks like it may be a root rot issue or the graft is being rejected; in which case there is nothing that can be done.
