you are icing for 4-5 min at a time? If so, the bodies response to ice in an increment less than8-10 minutes, is much the same as placing heat in the injured part. The adductor can handle ice 15 min / out of every hour. You may want to include some type of foam rolling / stick work to address tissue quality issues that you may have from the previous injury, as well as pain-free flexibility work.
