“How long should I have to wait for epidural with excruciating sciatica?”

I have stenosis throughout my spine but 3 months ago I woke up with awful pain and didn't know what it was. It's the same now 3 months later and I'm unable to get out of bed without help and can't rotate in bed and sometimes I can't reach due to it. It is radiating into my buttocks and back of both thighs, calves, and sometimes my feet. I am overly fatigued and don't get out unless I have to. I don't think that some doctors understand the severity of this type of pain. I had a bad tooth so I had to have that removed 2 weeks ago and free of infection before an epidural. The office called me yesterday and I can't get in for the epidural until Aug 4th., (does that seem like a long time out?) I'm shocked I have to go that much longer. I am including the impression of my MRI done 2 months ago. I don't know who to turn to and I'm on Medicaid and medicare which could be the Drs. don't care as much. I'm stumped and feeling left out. (Do I need a 2nd opinion?) Thank you so kindly
