Well just come back from physio & it's not a sprained ankle it's tendonitis. I def can't run till after my next app. 6th feb , & he's given me some excercise to do every day . I can cycle in low gear & swim . Well at least I know now . Still painfull & slight limp when walking , it isn't the achilies tendon it's located on outside of ankle . Anybody suffered from this , & how's it affected your running . Any info greatly appreciated . Physio said it's not seriouse & I should be good to go if do excercises & obey instruction , but after googling it , it sounds like it could be a on going thing .
