Hi Ava, thank you for your message. Again, I'm so sorry about your niece. I can't imagine having a child with this disorder (or niece) I have heard of ones getting RSD from procedures, even like a blood draw (the needle) so I ask for a butterfly needle which is smaller and less invasive as regular blood draw needle.
Even though I have full body rsd-16 years I still take precautions. even going to the dentist, as you can get it in the mouth. I take anti-biotics before appt. and use 'laughting gas' to relax. My dentist read up on it before treating me.
Mine started following breast surgery(benign tumor) got frozen shoulder (rsd) spread to other shoulder then feet-full body or generalized they call it.
It is tough. I would assume a cerebral angiogram is an invasive procedure.
I'm so sorry. Is it in any of her limbs? the hands and feet are critical to keep mobile- physical therapy has kept me mobile and using limbs, although one hand is permanently partial frozen.
I think the pain, medication, losses of all kinds, many of us deal with depression, so please watch for signs in your niece. Professional counseling helped me tremendously deal with various losses and coping with the pain etc.
The passing out is scary, I take my blood pressure kit everywhere, as that is my cue when it starts dropping, but I have passed out with no warning at all cracking my head on tile floor.
What does the Dr. say? She must have had something going on before rsd to have such a procedure. Her memory issues following events puzzles me. Take care, loretta
