Hi Heidi,
I'm sorry that you are having a really tough time right now.
There are soooo many frustrations dealing with chronic pain. Despite my experiences, I still get zinged with getting my hopes up with any new med or treatment, when I SHOULD know that 9 times out of 10, it won't help.
Do you mind me asking what you were taking before for pain ? Did you switch because it wasn't strong enough, didn't last long enough, or because of side effects ?
