Welcome RT to the forum and sorry your having such a time with pain,that is what this place is all about.
Too bad you cant find another Doc in your area to do the treatment as it looked as though you were getting some relief and maybe in time it would have been more. Is travel possible for you at all? It may be that another Doc can and does do it but maybe a hour or so travel might be necessary as alot of us have to travel to get to a Doc who works for us. I know you said your not computer lit well many of us arent but the more you play with it the better it will get but you can try a google search in your area and see what pops.
Also the vicodin is not alot to write home about as far as pain relief for chronic disorders goes and maybe talking to your Doc about getting longer more even relief is something it may be time for and I gather from your post that upping your med is not something your too keen on doing but you also deserve the best quality of life offered hence the long acting meds play out better for chronic pain.
The pain journal is something alot of us do to help as a learning tool for our potential treaters,it also played a very good part of my disability award as well. It kind of gets sticky at the Docs trying to relay when over the course of a month or 3 months we had pain the most and what instigated it as if your anything like me I do well to recall yesterdays menu must less something that occured months and weeks ago.
My Doc has even made copies of a page now and then and added it to my record on those times an increase or addition of a med has been needed,makes it simpler to make it part of my medical chart then his having time to jot a few lines to try to show cause.
Anyway good luck to you and I hope you find some answers here and if nothing else you sure will find understanding and compassion.
