Hi, I am new to the forum. I started cycling this year and really enjoying it and I find it very addictive. However,...my left foot gets really numb after about 30mins. I wear my every day trainers. And,......I am experiencing a terrible pain at the side of my right knee, not when I am cycling but afterwards. It is painful when I press on it. I do stretch before I set off, most of the time! Anyone any ideas?
