I have hard lumps in armpits after liposuction, is this normal?

In march I had a breast uplift and I have just undergone liposuction for the fat that was around the area,a week and a half ago now.I had lipo on the top of the right breast and left armpit area,I have just noticed two ball lumps just above left breast/armpit area and one lump in the same place on the right side, what are these? They feel hard and pea sized. Will they go? Are they dangerous? Is it anything I have done? Please, any advice/knowledge would be very much appreciated. Thank you
