Pain/pressure in knee and ankle when I walk or stand. Slight cramoing and pain in foot also whike resting, standing or walking. 28/f. Healthy.?

I would . Entertain the possibility of a mechanical cause such as a flatfoot or hyper pronated foot. Arthritic possibilities must also be considered. Finally, pain in one joint, could be the problem which ultimately causes pressure on the next...So a physical exam in person by a doctor would be a good idea.
