I feel for you, I'm very sorry that you have such pain! Sounds like you MAY have sciatica from the disc problem! Though Tom is right, my doc has read films differently from the Radiologist before too! But I would NOT go for a Myleogram, the dye isn't good for you, and they have had recalls on the dye, class action suit going on too!! Be careful with what you choice to do, we are all here for you, so please keep us informed!
They will probably send you to a ortho, pain management, neuro, etc., but you want to get many opinions too, not just one! You may still be treatable, sounds like it's fairly new? If it is, they may be able to give you an epidural of steroids to help shrink the disc? Don't know, but you do need to see a specialist of some kind, I would think!? Maybe others have more advice for you, so be patient!!
Sorry that you are going through such pain, I know it's hard, but keep positive, and know that you will get better!!
Best of luck to you, and all!! Wish everyone some sort of relief!!
