I have had a knot between my right shoulder blade and spine for years. When pressed gently I hit the roof and the pain goes on for ages. I think this is one of my trigger points, but now I think I'm getting one on the left and both kick off when I'm sitting for a while.
This morning my husband gently and lightly moved a massage roller over the area, which felt lovely, but I could only manage one pass. If this keeps up I will have to see the doctor but what can he do?
It's not shoulder strain from wheeling myself in my wheelchair as I haven't been doing that for a week, unless its that deferred pain? Whatever that is!
