Hi gus. I have been on pregabalin for some time now, although not the dosage you describe. It was recommended that I upped the dosage to very high amount but found that it made me into sleeping zombie! I am due to have another epidural next week in a slightly different position but have not heard about bilat facet joint injections - is this normally included with the epidural?
Perhaps I should try the additional dosage of pregabalin too.
I did have tramadol but it never did the trick for me. As mentioned in my post I am now also using a butrans patch 25 mg but this is also fairly ineffective.
It sounds as though you have major problems; Pain like this is so difficult to deal with and there doesnt seem to be any one solution.
