I am having pain in the arch of my foot. It's like my foot is stiff. My heel doesn't hurt just my arch. The pain is worse when I haven't used my foot. When i first get out of bed or if I've been sitting for a long period like at work. When I take that first step it's the worse. In the part of my gait where I'm rolling up on the ball of my foot and the metatarsals spread, that gets me every time. Could this be plantar fascitis? I read some on it but I'm not having pain in my heel. Does that make a difference?
