3 days ago I changed the inserts in my tennis shoes, I'm a nurse and work 12 hours so am on my feet alot. I changed the inserts cause I was starting to have some foot discomfort in the arch area. Halfway through the day after I changed the insert the arch on my left foot began to hurt horribly. I muddles through the rest of the day, thought that maybe I didn't cut them correctly so the arch was hitting in the wrong spot on my foot. The next day I went back to the original insoles for the shoes that had only been used for a couple of days when I first got the shoes cause I always replace the original inserts with Dr Schols Active series inserts. I worked another 12 hour shift and foot was still sore on the arch. The next day, this is day 3 now, the pain has moved from the inner, arch portion of the foot, to the outer side of the foot and is excruciating to walk. Not sure if this is plantar fascitis since the pain moved. It does seem to get better if I keep moving, but whenever I sit and rest for awhile and then get up to walk again its hurts. Any thoughts? It just confuses me that the pain went from the inner portion of the foot to the outer portion of the foot.
