i had a left mastectomy four years ago with reconstruction and reduction of my “ normal “ breast. I take tamoxifen. I am 53. I have suffered with this painful irritating burning prickling itchy arm that burns and makes my arm look like it’s been sunburnt. It’s driving me nuts and ruining my life as I don’t sleep well am tired and irritable and constantly scratching my arm making my skin very tender. Has anyone else experienced this ? Thank you x
