Jamie Moyer put this on his foundation's Facebook page today:

Thank you to everyone for your thoughts and support during this time. I went for an MRI yesterday and will keep you updated on what the outcome is once I hear anything. Have a great week and thanks again! – Jamie

We wish Jamie the best, and I hate to be a, um, hater, but it's time to hang it up.  It's impossible not to appreciate everything Jamie has done for the Phillies, the fans, and the community, however, there comes a time when you just need to move on.  Now is that time.
