I have breast cancer and I am going through chemo treatment at the moment. A few days ago, my ankle was very sore and a bit swollen. I just automically assumed I got bitten by a fly. I am on very strong antibiotics and was told to rest. It is still a bit sore but we are minding my sisters dog at the moment and she is very excitable and may have broken the skin on my ankle playing or something. I dont know. What do you think I should do. I am very worried. Liz
