What else can happen????

I have 4 Herceptin to go, am in the 3rd of 6 weeks of radiation, have about 2 & 1/2 months of blood thinner to go.   So, on Monday I was hanging laundry.  I lost my balance, fell backward landing on my already sore tailbone and left wrist.  Man did that wrist hurt.  I lay there a while, wondering how the ____ I would get up.   I did manage it, finished hanging the clothes,  did dishes, put ice pack on my wrist then called the PA-C office.  I wanted to know if someone there could check wrist so I would not have to go to er.  After several xrays, it was decided I had fractured the bone under the thumb.  I think Ulna.  They put a brace on it until I saw a bone doc last night.  I now wear a nice blue cast for 4 weeks.  They didn't have purple.   What next??!!
