My upper arms have gotten alot bigger, as if retaining a ton of water, as opposed to just swelling - Will this go away?

I just had my first procedure with MiraDry a few days ago and I understand that my underarms will be swollen and numb for a few weeks. But my issue is that, my upper arms have gotten alot bigger like they are retaining alot of water, bouncy, giggly, and heavy.. I thought it was swollen at first but like I mentioned it just feels like a ton of water is sitting in them.. Im worried, is this something that will go away with time?? Or should I be concerned?
