Are there any good stretches to prevent sesamoiditis?

Good shoes: Avoid bad shoes. Walk on whole foot rather then on toes or high heel., if painful need to see specialist.

Big toe pain: Big toe pain can be caused by sesamoiditis. Exercising the big toe by physically moving it dorsally and plantarly by manually exercising it while both standing and while sitting down may improve your discomfort. However, if the pain persists, you must have the big toe examined professionally where x-rays will be taken to rule out a possible sesamoid fracture.
