On Friday I tweaked my hamstring on set 2 of some flying 30’s. Our local track was closed for a High School track meet so I was running on grass but in my spikes. I just felt it tighten up so luckily caught it early. Weird thing is there is no pain at all duration palpation and rolling. I can lunge, squat etc. unweighted and slow running. I have a session booked with my therapist on Monday. I am assuming then that is is minor but very deep. Will it be too soon to keep the blood flow by the 10x10m drills mentioned in a previous post tomorrow or wait for the therapist to give me the diagnosis?
