Breast implant heavy

hi 

can anyone help me with this please

I’m 51 and ive just had a mastectomy with immediate silicon reconstruction on my left breast after being diagnosed with high grade DCIS throughout the breast. I’ve still got my drains in which will hopefully be coming out in a few days but when I went to have my dressing changed with my breast care nurse I thought all the heaviness and the feeling solid was due to that. It was only then I realised it’s not. When the dressing came off it was just as solid and just as heavy.

is this normal? Is it going to feel like this forever because if so I’d like it removed. I’d rather be flat on one side than have this feeling of having an alien inside me. 

Any feedback would be appreciated
