Brief answer....nothing to worry as it happens sometimes
Detailed answer....
Hello,
Thanks for the query.
This happens because of stool getting dried because of dehydration,less water intake on previous day,eating very less yesterday,not eating enough Fiber etc.
Once the leafing portion of stool becomes dry,it leads to impaction of stool in the rectum.
When you try hard,it would cause pain and may even cause tear in anal wall.
The best thing to do at the moment is either to use enema or use suppositories.
A ready made enema with the name of practoclyss is available in pharmacy and can be used easily or you can use rectal suppository like glycerine or dulcolax.
These methods would lubricate the inner lining of your anal  canal and help in passage of easy stool.
Steps to be taken regularly,so as not to get this problem again....
Drink plenty of water
Take plenty of fresh fruits and green vegetables.
Do regular exercises.
I hope it helps,however you may revert to me for any further query.
Best of luck
Thanks
