You are experiencing constipation
. Your stool is solid and cannot get out immediately. So, I suggest to:
- drink more water
- if no bowel movement, can take rectal enema
- take sena supplement together with lactulose
- eat more fiber rich foods
- exercise more
The shivering is due to extreme straining in the restroom and the pain you feel. If you do not have improvement after taking the above supplements, I suggest to consult GI specialist.
Until now, that is not something serious, but need proper attention to not to become serious.
All the best!
Feel free to ask me again if you have other concerns.
