What could cause vomiting, diarrhea, and painful urination?

Hi,

Welcome to icliniq.com.

I read your query and understand your concern.

Vomiting and diarrhea can lead to dehydration, causing painful urination. Keep him hydrated (at least eight cups daily). If the pain persists, consider a urinary tract infection. Confirm with a urine analysis and treat with antibiotics. For vomiting, I suggest using Metoclopramide (Metoclopramide hydrochloride monohydrate 5 mg), and for diarrhea, I suggest capsule Imodium (Loperamide 2 mg). Consult your doctor and take the medicines.

I hope this helps.
