I'm so sorry to hear about the symptoms you are experiencing. I would be happy to assist you further. Can I please have your full model number and serial number in a private message: http://bit.ly/2JH2rq2
@Samsung_r1fAgwU are you using the original watch band? Do you normally have sensitive skin or reactions to synthetic or metal materials? That looks very painful indeed, so sorry to hear about this! 😭
Would put some calendula cream on there or at least some coconut oil. You could put plastic wrap over coconut oil to leave on overnight. It'll be much better in the morning. Can put calendula on several times a day. Sorry you have this injury!
