Well, the physical therapy doctor we saw on Tuesday said she would not use the TENS unit on my mom because of the cancer. She said she is concerned that it would also stimulate the nerves and blood supply to the cancer. But, she did prescribe lidocaine patches to help with the pain as we try to cut down the pain medication as the radiation treatments reduce and/or eliminate the pain from the mets in her spine and femur. She does seem to be doing better, she had her 3rd treatment yesterday and was able to go 10 hours instead of 6 between pain med doses yesterday afternoon. So I am now keeping my figers crossed that through the next 7 radiation treatments it will end the pain altogether or make it managable with the over the counter pain meds. The narcotics (even at the lowest dose) really impact her thinking and memory negatively. Now I just have to get her to eat more, so she can be ready to try the IL2 in 8 weeks.
