Good morning!!! Thanks for your reply
...yes, any problem for/with my dad is definitely a concern for me. He has spoken with his nephrologist, nurse practitioner, and the nurses at the kidney center where he has dialysis treatments--no one seems to have a guess. His nephrologist works at a teaching hospital, which is a double-edged sword--great for cutting edge information, not so much for presence (he's into researching, lecturing, teaching, writing, and patient relations is last on the list).
Since last Friday, when some kind of new setup with the dialysis machines at the center, my dad seems to be having less of these problems. I live 70 miles from my dad and work, so I havn't been to the center yet to see what exactly the change consists of. If this solves the problem, it would be fantastic...I'm just the type that likes to know they "why's and wherefore's"...
Have a great day!!
