Approximately eighteen months ago I had a colonoscopy and in a following appointment the surgeon 'did something' to treat haemorroids. (I'm not sure exactly what - a quick physical procedure in my anus.)
Since that time I still have had blood in my stool from time to time.
The blood is always red (fairly bright).
It is usually 'on top' and kind of separate from the stool, and on the toilet paper.
I was told that the procedure on the haemorroids may not have worked properly and that I may still have haemorroids.
About ten days ago there was a lot of blood, the water in the toilet bowl was completely red, and I felt light-headed afterwards for about 12 hours. (I had strained a little bit, but not a lot)
The day after that there was a little blood 'on top' of the stools.
Then no blood, or very very little for the following days.
Until today when there was a small amount of blood on one of the stools.
I am male, 33 years old.
There are no other symptoms that I'm aware of. No pain.
Does this sound like haemorroids, or possibly something else?
Might it be the case that the procedure I had a year ago didn't get rid of the haemorroids?
Since I had that colonoscopy eighteen months ago, is it necessary to have another?
I would really appreciate any advice anyone might be able to give me.
My sincere thanks.
