Well, how long has it been that ur pain is causing you problems. Icing is a better option when the condition is acute meaning within a week to two. Give me a proper history of your injury. What was the date of injury? How long has it been? What are the aggravating and reliving factor? On what basis did u start the strengthening protocol? Which one is your dominant side? How long have you been running? What kind of lifestyle do you have, i mean active, sedentary? Do you any previous history of injury? Have you ever had the similar complains before? When did u first felt the tightness in ur Quads?
