I did something that a lot of players did, and tried to go back to the Soul Cairn after turning back into a human. But I saw that it was draining my health, so I went to Serana and turned back into a vampire.
After that, I went back to the Soul Cairn and after going through the portal, it was still draining my health. I decided to just go back, but even after that wherever I go it's still draining my health and I keep dying.
Is there any solution or command that could fix it? My last save was a lot of levels away.
