I've had this problem for well over a year and it's really getting me down. I've been to see a couple of podiatrists and as a result I have orthotics now which I wear all the time.
It has improved now end a few months ago I couldn't walk half a mile or stand for more than a few minutes without a lot of discomfort.
I went to see the Dr who advised me to take Ibuprofen as well, which would releive the imflamation that happens over night, which is why it's more painful in the morning, miraculously it made a huge difference, the only problem was that after a few days of Ibuprofen I got terrible mouth ulcers so had to stop.
Since then I have gone on for short periods, and touch wood, things do seem to be improving. However, I went to Budapest for New Year where I did a lot of walking and the problem did come back, but importantly didn't last.
I have learned to hold off the running while I have the symptoms as it does seem to make things worse again, so I don't know if I'll make a permanent recovery, things are definitley improving so I'm hoping for my gut sake that eventually I'll be able to get out there again.
That sounds like my problem. I read an article about it which said that it gets worse in the morning because your calf muscles tighten in the night.
Have you been stretching your calfs at all, I found that made a big difference, the pain in my feet is almost totally gone, and I'm doing some running again as well. I still have stiff ankles in the morning but it is getting better.
