Hello there , welcome ! First of all ,after bilateral mastectomies I did not have any pain,maybe slight discomfort,but nothing Panadol wouldn’t sort .I started off with 4 drains ,2 were removed before I went home . Volunteers at the hospital made these really handy bags ,you could put your drains in and wear across your body . Also we were given these little heart shaped pillows you could place under your arm when sitting down or lying in bed. Surprising how comfy that was too . In bed ,I just arranged my pillows into a triangle but you could get a special pillow . It was strange not being able to go onto your side but you get used to it .I bought myself some long shirt nightdresses ,buttons down the front .My husband had to wash my back for me and my hair ,otherwise I managed everything else .Good luck xx
