My wife was also diagnosed with rectal cancer and went through the radiation and chemo treatments. She had the surgery for tumor removal and a temporary ileostomy, the ostomy was reversed only after 2 weeks due to allergic reactions to the wafer and products associated. its been 2 long months after the reversal and the abdominal cramps and upper (internal) rectal burning is becoming unbearable most of this happens before a BM and shortly after. she is having on average 3 to 4 BM per day has anyone had similar symptoms what can we do to get through this does the pain ever stop.
