I was waiting for response from you.
Her symptoms can be due to IBS.
Infection can be possible too.
In that case, antibiotic would be required.
As the pain is too much, you can give Tylenol.
If the pain continues, she may need prescription medicine.
Then, you should take her to doctor for an evaluation.
Stool test can be taken.I hope this information will be helpful.
If you have any query, please feel free to ask.
