I'm Scared

I went to the PM this morning. After the latest MRI They want to to Epidural Spinal Injections. I know in my heart that this is the next step and probably the one to help the most. BUT.... I'm scared. It's not the epidural that I had when my twins were born. It's not something that I've gone through or even know someone who has.  I can even think it through that if something goes wrong I'll be better off than I am now. I could end up in a wheel chair (I'm there already) but I wouldn't be in the pain I'm in now. If it doesn't work I would just end up with meds. Not the worst case scenario. I really just need to hear from those of you that have been through this. I need to hear your success and yes the failures. I don't have anyone else that has been where I am right now. That is the best part about this group. I can ask the people that have been there before me. Thanks.
