I live at the doctor

I thought I pulled a muscle in my shoulder, it was almost better last Friday but the last few days it's gotten so painful that I can't get out of bed/change clothes.  So we called the oncology office, it's too late for an appointment today of course, and they recommend a vacation to the ER.  Ugh.  I already have two needles + mediport access and chemo to survive this week, really not looking forward to more poking and prodding and finding things wrong.
