For now I would suggest working on you base and do more solo steady state long rides and fewer group rides. Or do less work on the group rides. Cut it back to one hard group ride per week for a while. Try and ride every day even if some of the rides are shorter and just spinning.

You can also try massaging your legs with a roller.
