I put a dairy product called twaróg in Polish on the area around my knees because of muscle pain, it is a widely known "grandma's tip".
I think it really helps with the muscle pain, however, my skin erupsts in a light rash from this.
Can anyone tell me - does this mean my body does not handle this product well/is allergic to it? Does this mean I should use from "applying" this internally, i.e. eating it?
