just saw your title and was going to put my old post on but booktrunk as done it for me!
I had this back in oct 2012, really painful putting on my pants hurt and I couldn't stand on one leg as that was agony! I was referred to a physio and had X-ray which showed everything looked normal. Physio thought it was osteitis pubis, and tight hip flexors. I was very lucky that it cleared pretty quickly I took lots of ibuprofen, and did lots of strength excercises ( have a look online) stretching of the hip flexors and took complete rest for 1 week.
Was back running and touch wood the pain has stayed away but I do a lot of stretching and core/strength excercises religiously every day!
Good luck, if it dosnt clear up after a few days I'd see your gp or pay for physio if you can, especially as you are trainng for a marathon, they can assess you and give you the right excercises to do.
