Help...I am so discouraged and wondering if anyone out there has experienced anything similar. It has been 5 months since I developed a stress fracture in the metatarsal of my foot, probably my own fault from too much HIIT. It is taking a long time to heal, I am desperately missing the calm I get from HIIT and am seriously wondering if I will ever be able to do it again. At this point even most cardio routines are too painful and I am afraid of reinjury. Any suggestions?
