15 post-stroke, still relearning to walk. what type of scan is best to see what's going on in my thigh and hip? feel bundled up sometimes.

Nothing to see there: If you are rehabilitating from a stroke and having trouble walking then, there's really nothing to see in your thigh and hip. I will bet next month's mortgage on the statement, "They are BORINGLY fine." The problem occurred in the brain. You've probably had either the CT or MRI of the brain and that's what is really needed to assess the damage. Good luck with the rehab.
