"Nie potrzebuję leczenia."

Translation: I do not need treatment.

[JanuszWoro3]

What about "I do not need healing", or maybe ".... a healing" or ".... to heal"?

[Jellei]

So I asked around, and: added "healing", but I was told that "a healing" sounds like "a faith healing", and "to heal" doesn't mention the fact that I need more than just time (help, medicine) to become healed.
