Thanks Steve888 for your input. It's scary when you don't know the answer to something serious.
I'm nauseous but I'm going to try and drink some herbal tea, maybe some Gatorade. Any suggestions how I can have a productive BM? It's really starting to hurt all over my stomach area,my abdomen and I can feel it wanting to get out of me but there is a very bad pain along my transverse colon and where the transverse colon meets the decending colon...I can't get the waste past that corner, feels like an orange is wedged at that point. Also I can't push too hard;the lymphoma makes it hard to breathe much less push a weeks worth of fecal matter out of my body.
Many thanks for your help.
