Breast reduction 10 months ago but both whole breasts still hard?

Very hard breast but not swollen. Mainaly across the whole under side and outer edge, also above nipple. Rather than small hard knots the entire breast feels almost like one whole hard area? Is this scar tissue rather than necrosis? Does massage actually help? Also, no sensitivity in nipples but a dull ache is developing? Any advice would be appreciated especially as I'm approaching almost a year post op. I went from a J cup to an F Cup.
