Constipation

Detailed Answer:
Hello

Thanks for the query

It is unlikely that you have pain arising from the kidney because such patients tend to also have fever and are very toxic. However there is a possibility of a kidney stone.
Bowel moments depend on many factors like what you eat and how much water you drink.

Here is what you should do

1. get an ultrasound abdomen to rule out kidney stone
2. drink warm water, about 5 glasses a day
3. add fibre to your diet in the form of green leafy vegetables and fruits
4. syrup lactulose 15 ml at night will give you a good bowel moment in the morning
5. for pain acetaminophen is a good tablet, it can be taken three times a day

I hope I was of help, if you have any further queries please get back to me

Regards
