My 77 year old husband has stage 4 lung cancer and stage 4 prostate cancer. He finished immunotherapy in December 2025. He has had severe pain in his thigh for a year and is currently prescribed mst and paracetamol. The doctors don’t know what is causing the pain.
This medication was managing his pain but is not doing so well now.
I try to encourage him to exercise and although he will go for a short walk he lies in bed and sleeps till about 2 pm every day if he has no appointments. He does not seem to accept how bad this is for his pain.
Hello Liz C,
I'm very sorry to hear that your husband is experiencing such pain in his thigh.
I see he has both lung and prostate cancer and wonder if you've consulted both the doctors who are treating each condition? Bone pain can be a consequence of either cancer, but it tends to be experienced by more prostate cancer patients as it often goes to the bones with that.
I can't understand why his doctors appear reluctant to change his pain medication if the original treatment has stopped working effectively. If you're currently relying on his lung doctor I suggest you consult his prostate doctor if possible.
I see you've joined the lung cancer forum and suggest you also join the prostate forum and repost there. I've placed a link below for this.
I do hope you can make some progress soon to ease his problems.
