I had an issue with an adductor about two months, also caused by doing too much speedwork and I was pretty convinced that I might not get to go after my running goals this year. After a few weeks off, with no improvement, I changed everything up and focused on nothing but zone 2 running - monitoring my heart rate continually and being rigid about keeping it under my zone 3 threshold, despite normally running in zone 3. I cut out all speedwork.
It was boring to run that slowly. It was frustrating to walk hills that I normally run.
But after a month of it, I've logged more volume, more consistently than I have in ages, and everything is feeling better. Give this a try if you haven't, you might be surprised.
