I just changed out my whole appliance tonight. I am almost thre weeks post op with a colosomy. I put Cavilon skin barrier wipe first,then convatec stoma paste, then placed floating flange. It has been burning ever since I changed it. I haven't had any output yet, so I know it is not that. My question is, do I take this off and start all over, or do I just try and tolerate the stinging?
