Would you tell me what MSA means? Have you seen a neurologist, @kachris ? A few years ago I had started taking Lyrica, when one day I became incoherent and other things that were listed as possible side effects of Lyrica. I couldn't complete a sentence and lost my memory, along with other dire symptoms. I spent a few days in the hospital. So I had to stop taking it, unfortunately. It was the first medication that relieved the pain in my feet. Bummer!

Not being able to speak or write would worry anyone. I hope you find the culprit soon.
