Hi, I had my first chemo treatment for breasr cancer last Molnday and all went well. I have had no sickness and minimal side effects. However, yesterday I decided to go braless, as I thought it might be more comfortable and I wasn't going out. By the end of the day I had started to feel a tenderness and bruised feeling around the site of one of the lumps. I don't feel unwell or have a temperature and this has taken me by surprise. Should I be worried that I'm now experiencing this pain, it was not what I was experiencing, after treatment started.
