Hi there
I am so sorry this has happened to you. I am wondering if your rash may be related to your illness. I am hoping that you have called your doctor by now about this. It really could be anything from insect bites to an allergic reaction to...something related to your medication or illness. If it has spread this fast you want to get this checked out and soon.
Here is some general information about unexplained rashes and what to do. You definitely need to be seen by a doctor.
Please let us know how you are doing in the days to come.
