hi there
i to have just been through treatment for bowel cancer, i dont know what its like to have secondaries but if you dont feel right i strongly suggest ringing your doctor and getting checked out, there is no point waiting, i know its stressful but its better to find these things early than not.
How long was it since your last checkup?
I hope that everything is ok? Can i ask what type of symptoms you are having?
Kind regards
Stace
