It is not wise to delay a consultation with preferably a surgeon and get a check up at the earliest for the complain of passing blood with stool and have treatment after a proper diagnosis .
of the abdomen and dull aching pain through out the day should be checked for and investigated . It may be related to bleeding with stool or some thing else like some urinary problem .
and straining at stool may be responsible for your problem .
Please get a check up .
Hope you be all right soon
