Should I be worried if one breast is hard in places and warm to the touch after Breast Reduction? (photos)

Had a br 12 days ago. The left side was "fuller" right away but now it seems to be more tender, warm to the touch and hard in a area or two. It does not seem to appear to be getting bigger but the warmth worries me and the "harder" areas I had implants before, the left one broke so I opted for both to be removed then have a BR. I have been getting headaches and some hot flushes /chills no temp though so far. Thank you
