scapula pain

Hi,

I'm having a terrible pain between my right scapula and my spine, near to the scapula for precision. I'm having this pain for two years at least. Usually it feels like the pain going to my waist and my cervix (always on the right side). I tried to rest my arm but the pain keeps on coming. Now I'm visiting a physiotherapist and exercise as I was told, but I don't see any difference. I had x-rays and MRI but they didn't show a possible reason for the pain. Is there any advice I can get for this?

Thanks
