If you're having an issue with your hip flexors, then take a week off and down some ibuprofen then carefully work on your squat technique. It's quite possible that your knees are sliding forward in the hole, which tends to cause that issue. Start light, avoid anything that causes an increase in pain over time and make sure to warm up thoroughly before you squat. My warmup is five minutes on the rowing machine, then twenty leg swings each side and twenty bodyweight squats (along with twenty arm windmills as I find squatting can be tough on the shoulders). Keep us posted.
