Hello and welcome. I'm Dr Chip
Does the pain radiate from one side of your back around to your groin?
OK. My first thought is that this is a kidney stone. Those usually pass in two or three days with plenty of fluids for hydration.
The other possibility would be a lower back disk problem.
You need to see a doctor for an exam, urinalysis and possibly a ct scan to determine exactly what's going on here.
Please let me know if you need any more information.
