What could be the reason for severe stomach and back pain after diarrhea?

Hello,

Welcome to icliniq.com.

I understand your concern.

Both abdominal and back pain can occur in diarrhea due to muscle spasms. As inflammation goes on, it causes the release of toxic products, which cause muscles to go into spasms leading to pain. But about diarrhea, I would like to ask some questions:

1. What is the frequency of passing stool?
2. Is there blood in the stool?
3. Did you have any outside food?

I would suggest getting a stool culture to know the exact cause of diarrhea and the take the following medicine:

1. Tablet Diclofenac and Dicyclomine for pain.
2. Take ORS (oral rehydration solution) for diarrhea.
3. Start with antibiotics when the exact cause is known.

I hope this helps.

Thank you.
