It is best to see a professional for physical evaluation like a podiatrist. You may need to be evaluated especially about your foot wear and probably for surgical intervention to correct the concerning deformities. You should wear wide width shoes; rather than the tapering shoes that may have contributed to the current situation, though fashionable they may be.
