Ok, thanks for your advice.

If that is the case then what would be the next step? Let the Tendon heal itself? Or would you normally have an op for something like this?

As I say there is no pain in the actual shoulder itself nor from the tendon that goes over the top of my shoulder (fom the bicep). The pain is right at the very front where the tendon inserts from the bicep. No pain when my palm is facing downwards.
