Sore biceps for over 2 weeks with no reason. I mean I know they'd hurt after a workout but this is a sharpe and them pressing pain comes and goes?

Biceps. Having equal pain in both biceps concurrently would tend to indicate some irratative activity. Think about what has changed recently in either what u do or how u do it. If trial with gentle stretch , ice , NSAIDs don't improve things u should be seen.
