I have just had day 5 of 20 EBRT radiotherapy treatments. On day 4 and again today I felt a burning sensation in my pelvic area / lower abdomen. On day 4 it lasted two hours, today it is still there 4 hours after treatment. It is similar to in some ways to nausea but different. This does not surprise me as this is what one would expect I guess. I am just wondering what others have used to reduce the sensation - if this is possible.
