Itchy reaction 1 year post op. Is this rash normal? (Photo)

i had a breast lift and reduction jan 2023 and i notice now a year and some change later i get these itchy red bumps. It’s not extremely itchy and honestly doesn’t bother me much, and weirdly only happen at night? and usually the left breast and it seems near the incision from the nipple down, but not exactly on where the stitches were. they’re about a size of a quarter and red and don’t seem filled with anything. and it always goes away when i wake up. is this rash normal after 1 year post op?
