Many years ago I had axillary clearance with a mastectomy. Today I have the weirdest itch. I am numb where my lymph noes were removed so I cannot scratch the itch, even though it is so very itchy.
It's the old nerve endings, sort of like the phantom pain or itches amputees get in their missing limb, my dad had his right arm amputated after a car accident and used to say it felt like his right hand was itchy at times.
