I’m sure you will be fine everything you are going through sounds oh so familiar i had the hot flushes felt like i was going through the menopause some days haha i have regained sensation in one breast but the other is still a little numb, my nipples have became hypersensitive at the moment and i am getting more movement as the days go by, one breast is starting to soften and the other is still quite firm and swollen so they kind of look lopsided in tighter tops, as for sleeping i would suggest investing in a v shaped pillow they are a life saver for keeping you in place during the night xx
