Is Excess Hair Growth A Side Effect When Diagnosed With Breast And Liver Cancer?

I was diagnosed with breast and liver cancer. I went on a trial and for 1 yr received 4 doses of Herceptin per month and 3 doses of pre-meds plus paclitaxel per month. The liver cancer is resolved and the breast cancer reduced. For 3 months I have been on 3 weekly doses of Herceptin only. Since ending the chemo, and only on Herceptin, my energy and memory are coming back and I have stopped putting on weight. My hair, eyebrows and eyelashes have started to grow back, but hair is also growing on my face longer and whiter than before. I also have a rash over most of my body. It can t be seen, but it feels like every hair follicle is raised. Can I do anything about the bone and muscle pain (especially in my feet and fingers), the rash and the excess hair on my face?
