When I read your post it was like 'dejavu'. I also find my shoulder blade area feels like a bruise but without a bruise. My mast. was Jan 05, (8 chemo no rads) found I couldn't sleep properly on that side for about 9 months.
Jan 06 mentioned shoulder pain to GP. who ordered CT scan which only found cysts in my liver. Its probably nerve endings still healing and just something I'll live with till they repair.
Best wishes
