I had an accident 8 and a bit years ago which lead to plantar fasciitis in my left heel. I had loads of physio which fixed it.
In the last month or so I've noticed that I've started getting those pains again in my heel. No where near as bad as before but weird and annoying and a little bit worrying! 
I don't wear heels - spend most of my time in DMs or trainers.
Can anybody help or advise me?
My precious GP was useless with all aspects of my injury last time.
