Textured implants sudden softening after 6 Months

I am 6 Months post op with round textured 385cc under muscle. I was very flat chested before hand. My implants have always sat quite perky as if I was wearing a bra and were pretty firm. A couple weeks ago I was adjusting into a bra and must have been too rough as my breasts were aching as if I was 1 week post op. All of a sudden once the pain went away my breasts became softer with a bit more movement. Even my partner noticed. Is this normal? What could have happened?
