<font color="blue"> first of all, my prayers and thoughts are with you and your family.....*hugs*

my mother has suffered from the same exact symptoms for years........
she suffers from RLS, restless leg syndrome...

i wonder if your fathers doctor had looked into that at all???

my mother was misdiagnosed at first, but then got a second and third opinion and it turned out to be RLS.....

she was 2 weeks away from having uneeded surgery!

just a thought.....

i hope all goes well..... </font>
