Hello,
Do you use a laptop regularly? Or sleeping regularly on your right side all night? I ended up seeing a osteopath when I had a problem sounding like yours. I went a few times and he pulled me about a bit, and suggested putting something cold on the area. I used one of those pads filled with barley (I think) that can be heated in the microwave or chilled in the freezer. I used it chilled on the area every day. After a week or two, the pain disappeared. I have also bought a new pillow to sleep on. Hope this helps you.
