Bumps On Fingers, Painful After Touching, Cold Sores Every Month. What Could Be This? Suggestions?

I have these bumps on my fingers that hurt when I touch them or when my phone touches them, etc. They aren't visible, I can only tell they're bumps when I touch them. I get cold sores every month or two and I take valacyclovir episodically to make them go away. I was wondering if they could be from stress like the cold sores, or what else they could be. They are very annoying and I just want them to go away. My email is YYYY@YYYY
