My husband has stage 4 prostate cancer which has metastasized to the bone. He was diagnosed in 2015. His most recent treatment was docetaxal which lowered his psa for about 3 months. This week, he starts Jevtana which I hope he can tolerate. He still suffers with some neuropathy in both hands and feet. Recently, he's been complaining about a severe headache which he's had almost daily. It does improve if he takes something very strong like hydrocodone. His last bone scan showed no change, but I'm afraid the problem is much deeper. Has anyone had a similar experience with headache pain?
