Hi, I’d like to ask if anyone has any advice about burning pain in the evenings as a result of metastatic bladder cancer. (Stage 4). My dad is experiencing a lot of pain particularly in the evenings. He is having immunotherapy as treatment as the chemotherapy didn’t work. He is obviously worried but he is ok in himself but the pain and burning is what is getting him down. I read that bi-carb can help with this, is this a proven thing and if not does anyone have any suggestions regarding this please. I’m desperate to help him xx
