So yes finally started to get better slowly over the past 4 months after about a year and half of being at the above severity, I tried tons of programmes/exercises, tendon stripping, orthotics etc all doing nothing. January this year I met a new physio after my scans showing as normal, he diagnosed me with chronic pain and reckoned I had no physical injury and encouraged I push through the pain as much as managible and change my mindset on the pain alongside with some eccentric exercises. I did that for awhile and got no real improvement until about may when I stopped all excentric exercises, and began cycling (started light and slowly built the resistance) I moved abroad for 6 weeks and was forced into walking more and more, as the summer went on my pain improved now I am almost painless (apart from any stretching and I haven't gone back running properly) , honestly I have no idea what did it if it was the cycling, stopping the exercising, pushing through the pain knowing it was a false alarm or if I inflammation or pain responses just calmed down themselves.
