Well it’s probably going to burn a little whenever you take a shower. In terms of time that’s difficult to estimate since everyone has different times for healing and we don’t know how severe or large the patch is. For reference, I’ve had boiling water burn my fingertips a couple times and it takes about 4 days to a week to heal enough so that I don’t feel it anymore, maybe add a few days until it’s gone for good. Your arm will be different though
