Breast has gone weird shape!?!?! Why???

I had a revision 9 months ago and the results were fantastic.... until yesterday night, I took my bra off and saw this horrible looking boob (see picture). It’s been abit achey the last few days and has been looking a little off but I didn’t think it was anything until last night. I thought maybe my bra was too tight so slept it off and wore no bra all day and it is still totally distorted so it’s something going on inside. Does anyone know what this could be. I’ll call my plastic surgeon on Monday.
