Call it the renewable of pain (dukkha). Our problem is the way we misperceive feelings as itch, pain, etc. instead of perceiving vedana as vedana. We have many terms for vedana because we classify types of vedana. That way we don’t perceive vedana as vedana but itch, pain, cold, hot, etc. We must know vedana (feeling) and sanna (perception/misperception).
Sakkaya Ditthi is our problem here.
