The answer so far to why my hip is causing me so much pain is: I don't know.
The x-ray and CT scan I had Monday revealed that nothing much has changed since the last scans. Possibly a tiny bit of growth in one part of my hip tumor, but nothing substantial, and no additional fractures that would set off any alarms. (My lung tumors have stayed the same, except for the big one that keeps growing, but my oncologist doesn't want me to do another round of chemo right now. Maybe later, maybe a different form of chemo. Or maybe we'll have to start looking for clinical trials — argh, so much to think about.) I'll be seeing Dr. S. tomorrow and an orthopedic oncologist next week, and maybe the radiology doctor, too, but so far, at least over the phone, no one has been able to put a finger on what's causing the hip pain.
Meanwhile, I can't sleep without Vicodin, and even then, changing positions is painful. By day, I glide rather gracelessly around the house in my wheeled transport chair, bumping into corners and doorways. It's really frustrating to have a new set of limitations thrown in my path. I hope this turns out to be nothing but a major muscle strain caused by overuse during our trip. I hope it's not permanent. Because then we'll have to start thinking about how to outfit our house, yard, cars, etc., for wheelchair access. And that's not a project I want to worry about right now, on top of everything else.
