I had so far two injections in my back. The second one I had this past Thursday and was terrible. I still have numbness in my left leg from upper thigh to ankle. Also I have horrible leg pain and this is why I had shots. I thought when u have these shots they need a MRI to know where the source is and to also know where to stick needle. My pain right now is a 11. I have pain meds that are not working at all. 10 mg lortabs. I was on oxycodone and he took me off that. I see my back surgeon this week and maybe ask him what is going on.
