You Say You're Disinfecting But You're Sprinkling Salt On My Wounds: This phrase conveys the metaphorical idea of someone hurting another person even more under the guise of doing them a favor. Here it is expressed through the painful yet common metaphor of 'salt on the wound', meaning adding further pain or distress on top of what was already there.
