I just got a cortisone shot 2 days ago for a bout of PF I was dealing with for the past 3 months. How long should I wait until I start running again? Doctor said 10 days and given that I haven't run in over 2 months trying to treat this damn injury it is not really that bad. Could I return to other activities like biking or swimming before the 10 days or should I take a complete break from all activity?
