I recently completed and radiation for breast cancer. I have nueropathy as a side effect of the Taxol. tonight I discovered a "rash" on both legs from hip to ankle. It consists of bright red spots that have diameters that range from 1 mmm to 5mm. I will be calling to make an appointment with my doctor in the morning, but I want an idea of what is causing this. Thank you.
