update

You asked how old i was,im 36 yrs old.
The quantity of stool i pass each time varies but gets worse as the day goes on,but i never have to go during the night.
There is no blood or mucus in it.
They do soil my under garments
I didnt have any abdominal until a few days ago,now i have a constant stitch pain i n my right side.
Im quite sure ive lost weight as my clothes are getting baggy on me.
Ive never been one for sleeping to well
My G.P as told me i will need an internal if the symtoms dont side by the time i finish my course of fybogel
I have not taken any other medication for this problem,but do take other meds
Cocodamol
Atenolol
Thiamine
Vitamin B compound
Ive been having this medication for 2 yrs now though,so cant see why this should be the cause.
I have no other illness
