Odd

So this year, I’ve had an odd problem on the bike: within minutes of getting on the bike, I develop a fairly intense pain under my right shoulder blade.

Where this is unusual is that the pain is local only to that area and right next to my spine. And it seems to be muscular. There’s no pain in my neck and no pain in my right shoulder.

Anyone out there have any ideas as to why this is playing out like this?
