Sorry for the typos.
Hang in there. Keep at it and never ever give up or give in. Reach out any time.
I'm just starting my first year re-check for cancer and hoping I'm still .all clear.
The bowels, mostly function but do admit there are times, I have to get to the bathroom promptly. And of course little, or a lot, it hurts in the rectum no matter what. I went through the diarrhea aspect for quite a long time so know how awful that is. I had to have repeat sigamographies and sometimes I could go through with them because of the pain or either because of the backup. Some days, I continue to wear my pink "diapers" just in case.
As far as pain externally, the sole product that provides instant relief is a product made in Sweden by Stryker called StrataXRT, but haven't been able to find it carried by the pharmacies here in the area. My radiation oncologist provided a sample and it was soothing. Of course that won't help internal pain I don't think.
