Hi just to say that after roughly 4 weeks of a daily 3x100 mg PREGABALIN I find that I am having problems when going to the toilet in that I am constipated and as a result have to press. because of this I am reducing my daily dose to 1x100 pill. and already after one day my legs are starting to get sore again. Just when I thought that with a combination of Pregabalin and the Tens machine was the answer. We all live in hope dont we that this pill or that pill will do the trick but at what side effects.
