It does get easier honey over the next few days,your nurse will instruct re the shower,I was just having shallow baths to clean myself avoiding washing anywhere near the dressings,I know you feel grubby,and that makes the pain seem even more intense,it will ease off honey,just rest as much as you can,while your resting your healing,give the nurse a call she may be able to advise re the painkillers,I slept elevated for two weeks my surgeon advised this to help reduce the swelling.I know its difficult feeling disabled and the simplest of tasks seem so difficult,if you do something and it hurts,that’s your body telling you not to do it honey,hope you have some support at home,big hugs,xxx
