I haven't had a cold sore for 10 years.
Small lump appeared yesterday on inside of lip, has grown bigger and raised (like a cold sore) but it's not actually on the 'lip' part - it touches the border but is on the inside.
I've looked at cold sores pics (nice) and they all look like they start at the outer edges of the lip, mine starts inside the lip - so when my lips are closed you cannot see it.
Is this a dreaded cold sore or something else?
