Hi I'm new here!

I'm a part of the support team for my dad who is fighting stomach cancer he was recently diagnosed a few months ago but this is an aggressive form of cancer. He has also survived prostate cancer and also pancreatic cancer and 2 strokes over 20 years ago so this is third bout with this horrible disease he is scheduled for surgery to have it removed on November 29th but he is waiting for tests to come back to be cleared for this surgery. As of now doctors have said it has not moved out side of the stomach or area where it started but he is dealing with a lot of pain in his lower back on his left side and pain in his hip and thigh on his left side and is also complaining of his lower left leg feeling numb He Has Fallen last week from losing his balance and within the last 2 weeks he's visited the ER for unbearable pain. They gave him steroid shot and pain meds but not seeming to find relief. Is there anyone out there who's experience relates to this?
