I want to know if I am able to get rid of the disease after I didn't burm those other heads of those witches, just the one for the ghost, but I still have them, but I went back to the place with fire and there's no way I could burn them again
Do I have to load ? I made lvl 55 during the latest quest for companion and I don't want to load that far :/
Thanks

Yes, you can. http://www.uesp.net/wiki/Skyrim:Lycanthropy#Cure

Throw a witch head in for yourself.

iirc, you can only cure yourself during one if the quests to cure the other companions

Anytime after the companion quest to cure the dead leader. Just take a witches head and toss it into the flames. Just as you did for him

It won't work if you don't do it immedately, if you leave the burrow you won't have the option to cure yourself until after curing the twins.

I had that same problem on one of my character and what I did was place the witches head that I had in my inventory into a container a different one that I had the others heads and then take one of the other heads and try again and that worked for me
