Sorry to read of your husband's diagnosis and the tummy cramps and nausea he's experiencing.
There are medications that can be prescribed to combat these symptoms; I was given Domperidone for my nausea. Give your husband's medical team or GP a call on Monday morning and let them know what he's experiencing. If Monday is too far away, it may worth going to your nearest NHS Walk In centre for advice / a prescription. Hope this is helpful.
I don't know if there is any respite but just wanted to send big hugs.
My husband was diagnosed with stage 3 bowel cancer in September and has just finished 6 weeks of radio therapy and chemotherapy. So am in a similar situation and share your feeling of helplessness. Big hugs again an xx
