Had the injections done Monday, that night started the diarrhea..runs out like pee

. Felt what I thought was a little relief from the pain before the above began.
Have left a couple of messages with the doctor, but so far no call backs.
Just wondering if anyone else might of had this after an injection?
I had 4 injections. Lower Lumbar.
I have been re reaching and have found nothing about this being a side effect.
Thanks
