Hi Darren,I do feel for you,mine also started in June and like you I ignored it,was even told by a very experienced runner that if I ever got a sign of PF treat it immediately!! I thought Ill be different!! How stupid.. Able Feet to answer your question,I started this thread as I wondered if I could still marathon train after it first really stopped me in my tracks,thinking it would clear up in a week or so!! Mine started in June very slight,kept running and was always ok,ramped it up in August for half marathon mid oct going for a PB ! 5 runs a week,1 day speed session as well as a 21min 5k every week.. On top of this I worked 3/4 days per week evenings on my feet sometimes 5/6 miles on hard floors.. The running was still ok but by Sep walking at work hurt(out of 40 of us there,8 have pf!) Had it strapped for half and it felt fine,started off,doing well,fast,mile 5 pain so bad it stopped me in my tracks,couldnt walk for 2/3 days and had it diagnosed as bad flare up of PF.. Somedays I still limp all day,other days its fine,was getting better then I started running last week only 2/3 miles and now back again.. I run mid foot and I have run a lot this year in racing flats.. I hate the feel of big padded trainers,as I feel trapped and am now too trying the barefoot route,have got some vivos but they kill me at the moment,walking barefoot as much as poss too.. However Fat B, today while I was out I found some Fit flop shoes in sale! Felt great when I tried them so got them for work! I will listen now and stop running and hopefully it may get a little better.. Icing morning and evening really helps Darren,immerse foot in full bucked/basin freezing water 10mins,try twice a day and last week before I stupidly ran a 5k on Sat the barefoot walking in the house really helped,but not enough clearly! Thanks FB for taking the time to give me suggestions,it does help to know that other people have had it as badly as me and that it will go(I hope!)Guess Reading half is out of the question...!!
