The pain of PF is too severe for Ibuprofen in my opinion but is a localized thing which makes the Baxter nerve idea most obvious in my case. Also my cortisone experience was positive as I noted the nurse practitioner indeed placed his needle right about there where the 'Baxter nerve' would be... and that pain's been gone (in my then more hurtful left foot) since... whereas the non treated foot now still has twinges of PF residual aches here and again.
on the previous message, I am sorry to hear that the US Army still doesn't provide adequate fitting boots. I recall as a teenager working a summer or two with those Army surplus boots I could only afford (5 bucks a pair).. and my feet have never been totally pain free since. that was about 30 years ago. I would have thought the Army by now would have invested in some of the new shoe and boot technologies that have revolutionized mountaineering and skiing.
