Is this herpes? Please help

So about a week ago i notices noticed what seemed like a small open sore around the back my jawling. I didnt think much of it but its been spreading and it wont heal. Its just open sores that kinda just have puss form on them and the occasional small little blister forms and turns into one. It doesn't really hurt all that bad at all. The blisters are painless and the open sores or just irritating, its not to painful

Also, how do you post pictures onto a discussion so I can show it for a better answer
