In recent remission, but symptoms remain

Think my surgeon was surprised when sigmoidoscopy showed no evidence of cancer last month! Of course, I was thrilled, but still worried. She had been telling me about how she’d already asked surgeons at MD Anderson and elsewhere whether her patient (me) would be better off with permanent colostomy or might do as well with colostomy, then reattachment,  because my anal cancer tumor was so high in my rectum, which is unusual.

When I came out of brief anesthesia for sigmoidoscopy, she said, “Will see you in 3 months to test again,” which I gather is the practice in first year.

i keep thinking my next sigmoidoscopy will show I still have cancer. Was stage 3c. Also my stool is the same, skinny and often short, and usually pops out with a poof of air. My temperature was 100 during follow up 10 days ago with radiologist; before and during treatment it usually was 99 something.

Both the radiologist and surgeon asked if stool was still unusual, and I said yes. Is this common in remission, or should stool and temperature be more like they were prior to cancer? 

Finished standard treatment in early April, and in late June/early July, had fluid in my lungs, which my pulmonologist thought was sign cancer had metastasized to lungs. He was was wrong, thank goodness. (I have mild case of pulmonary hypertension) I am convinced it was delayed reaction to chemo, same as thinning hair, which still is going on.

. Docs all seem to be saying different things. Am happy to be in remission now, but confused. Want to start exercising more, but don’t seem to have energy.
