Hi Mke1
I have the exact same problem! I'm starting to think that its from something
i've eaten that is causing the stinging and I know! its really sore! I usually let it sit open for awhile to get air and put some powder on it although that stings for abit. When I put the flange back on , I make sure there is no powder and I use the spray. What do you use? Then I apply heat for about 20 minutes. Sometimes it works, sometimes not. This week its unstuck every day! Grrrrr.
