Same with me. 41 and never had a problem sitting until about a month ago. Left leg goes numb and/or hurts. I do pretty intense strength training at lunch 4 days a week, but it's not enough. I now have to get up and walk more during the day or even alternate between standing at my desk and kneeling.
