I've recently started running and find that all of my joints ache ALOT. I workout regularly (elliptical trainer for cardio about 45 minutes a day + 30-45 minutes of weights/stretching). I've always had a bad knee and a tendency for a ciatic nerve to flare up in my back. Should I just give up on the running thing altogether or push through? I've been living off of epsom salt soaks and advil for the past two weeks and still can't run very well, but when I can run well, I love it! Help!
