So sorry to hear that! It's like I could have written your post--all the way down to the specific workouts you do--so I definitely sympathize. I had a lower back injury at the beginning of the year, shortly after beginning training for a half marathon, that sidelined me for a few months. Even now, it still bothers me…

Definitely take one day off per week. Your muscles need to repair themselves, and not allowing them to do so makes you more prone to injury. An injury will just slow your progress down. Also, I personally always notice an improvement in my stamina, energy, and form the day after my rest day.
