Maureen!! I totally agree with you. I have spent way too much money on this to give up now (and am continuing to spend money with this injury).
I went to the Orthopedic Dr. yesterday! He says I have Plantar Fasciitis! I figured as much. I guess I was pre-disposed to it after that injury I had 5 years ago (which likely affected my Plantar Fascia, leaving it prone to re-injury).
I was expecting to be given arch supports since it is my arch that is hurting so bad, but they gave me Spanco inserts (which, granted, do have some arch support in them), and added a slab of outer foot support all along the outer edge! I was very confused by that... But, I am going to wear them religously for the next three weeks and see how it goes. If they don't help I will go back.
The thing is, I am really not sure when I should start easing back into running again. The doctor just said to "take it slow"... well what the heck does that mean?! That isn't very specific! But, I think I will start going for 30 min walks 4 times a week or so... and when my feet stop hurting while I walk, maybe I will ease into running from there? Idk.
And for the record, I still haven't finished the C25k!!!
I finished week 8 and that is when my foot started really going crazy.
