Oh, we all feel for you strav. Even if you stretch properly, faulty hip alignment will expose you to this risk. Ofcourse you have to look at your complete alignment, right up to the tip of your head, but think of addressing all of the muscles that connect your legs to your hips. Hurdler's Stretch both forward and to the side will directly address your present issue; take great caution and err on the side of caution with this one. But your hamstrings and outer thigh(always ignored) also impact the turning action in your swing. So stretch your hams, try laying with your butt up against a wall and stretching your legs out. If you can't stretch your legs straight you have to move back. Hold this passive position for
1-3 minutes. Then for the outer thight lay on your back and cross your legs (yes like a girl) and then let your legs fall over to the side that places your instep toward the ceiling. This stretches the pesky iliotibial band.

Look at strengthening your gluteal muscles. Not only from a perspective of power but of access to the muscle. When we use our hips to drive the drive, weak glutes overexpose your inner thigh system.So look at lunges and safety squats and other lower body compound motions to get the power of this muscle to serve you.

These are only a few of many potential exercises. Don't get overly focused on stretching the groin to the exclusion of the rest of this huge joint. It would leave you at risk of another injury once the symptoms subside.
