I was saying yesterday on another thread, that a friend of mine with scoliosis ie curvature of the spine n various other medical probs had fairly recently asked if she could change her pain medication to pregabalin after another mutual friend having asked her last summer if she'd ever tried it, cos she'd heard good reports of it from people she knew. Six months later, by now it's had a really massive, virtually whole body, good effect for her. Everyone's body is different and the only way to discover whether it suits yours or not, is literally try it and find out!
Her neurologist told her upfront that it could take at least weeks if not months to make any difference so she didn't really share her good news with anyone except her husband for ages - but she now feels comfortable that it isn't just the placebo effect and wishful thinking on her part, so has started to tell people.
