So I have a cold sore on the corner of my mouth and it has been hurting for a few days so I squeezed it and puss stuff came out is this mersa?

But if you are otherwise healthy and this is not getting worse, you ought to be able to just ride this out. ...Read more

I had a cold sore for three weeks and I don't know if it's healed yet. It's still a bit red but I'm thinking maybe it's just a scar. Is it contagious?

Not likely: If you had a cold sore and all that remains is some redness, it is probably the result of the inflammation remaining after the cold sore ran its course. If the little white or clear-looking bumps (called vesicles) have dried up and gone, the area is no longer contagious. The virus that causes the cold sore can certainly be spread to others when the vesicles are still present. ...Read more

I am prone to this cold sores and even have one now about three days ago I noticed a small bump on the left side of my tongue it is not painful I was just wondering if it could be a cold sore spread into my tongue or my health anxiety makes me think it's

Not a cold sore: Cold sores occur on the outside of the mouth/borders of lips, not in the mouth and are caused by the herpes virus. Canker sores, which are not caused by the herpes virus occur in the mouth, and are typically painful. This could just be an enlarged tongue papilla, which is common and not a problem. Have your doctor check it to be sure. ...Read more

I have a small bump on the left side of my tongue that I noticed about two or three days ago. I also have a cold sore on my lip I was wondering if the two could be related? I suffer from health anxiety so this is making me think I have oral cancer

Don't jump to cancer: You are right to think about your health anxiety - and you'd be right to get that under control. There are psychotherapists who specialize in this type of anxiety - it's fairly common. But the probable connection is a virus (herpes) or something like that and you can ask your Dr or a pharmacist for symptom relief. Canker sores should go soon, so if it lasts - see your Dr. Best! ...Read more
