Is it normal to be having a lot of pain and hardness in my breast implant after having a lumpectomy? (photos)

I had breast implants done June 2015, in Oct. 2016 I noticed a lump in my right breast. I had two mammograms, a marker inserted, a needle biopsy and finally a lumpectomy. Since the surgery I developed pain in my collarbone as well as felt it become harder. I can not sleep on my right side or stomach. When I lay down I feel intense pain. My right breast has become extremely hard. I feel like it's sitting higher in my chest and sometimes that it shifts towards my armpit/side. what could be wrong?
