I'm thinking more of where the bicep connects to the tendon at the elbow. The bicep is more responsible for twisting the forearem than the actual forearm muscles are. That pain will manifest itself in the forearm moreso than in the bicep, at least when the arm is at rest. Where you'll really feel it though is if you try to do a simple curl. You'll feel that pretty much from your mid bi all the way down to your wrist.
