My right foot has been painful with no relief from ibuprofen. While walking it cracked which caused extreme pain and made bearing weight impossible. I can walk on the heel but cannot roll the foot forward due to intense pain. The cracking has happened before and x-rays did not find any breaks. The foot is bruised on top right side (little toe side). Last time my middle toe bruised. Icing, compression and massage help some. My orthopaedic doctor was unable to determine cause of painful cracking. Any ideas what is cracking and what I can do to prevent it from happening?
