After inconclusive appointments with my chemo oncologist and a radiation oncologist in the past week, we finally met with an orthopedic oncologist yesterday who gave me some answers about my hip.
Yes, a basic muscle inflammation brought on, probably, by overuse during our trip. Just as I'd wondered, but no one could tell me until yesterday.
So I'm taking three Advil at a time, three times a day for 10 days (if my stomach can stomach it). Meanwhile, I'm already feeling better, and now I can walk around the house again with my cane, as long as I don't overdo it. Ibuprofin, rest and physical therapy are the doctor's orders. I can do that!
