Hello there. I am new to the board, and this site was recommended to me by a friend who once used this site for medical advice! I am a 26 year old female, and I have been tested STD-free over the years. I have a problem right now, and I was wondering if I could seek out some medical advice since I do not have health insurance. I researched canker sores and oral herpes because I know they can both occur in the mouth, I at least know that. I even found a couple posts on this site with people with similar problems, but I can't seem to get a straight answer from the information I found. I recently moved in with some friends, we're rooming together for college. One of my roommates gets cold sores, and she has gotten them for years. Well, I never really cared until I moved in with her, and now I'm overly concerned about contracting the virus. How easy is it to catch? The reason I ask is because we have communal silverware and glassware. My other roommate is concerned too. I recently noticed that i developed a canker sore on my gum above my front right tooth. It hurts, and I have never gotten them there before. I read that canker sores usually only appear on unattached oral tissue, and that herpes sores develop on the attached tissue. I'm a bit distraught, as you can see. I don't share anything with her...food, drinks, utensils, lipsticks...anything. So, I hope I safeguarded myself good enough. I wanted to ask this board before I paid out good money to see a doctor in person, and also to see if this is anything to be worried about. What do you think? Are we at risk of catching it? Does my mouth sore sound like a canker or a herpes sore? Thanks for your advice in advance!
