Hi there my dear..... It is not any kind of fun at all to deal with. I did not think of it being rsd or ms till I showed the dr what going on.. Felt weird n was really hard too walk with the back issues that I dealing with anyways....  Dr said o dear....  Arches are being broken n toes are turning also  dealing with hammer toes.. Get it all corrected ,,,,  asap. We have too take care of what we can... And do all that we can... Foot dr will tell you to get into new balance shoes. They are only ones that has the fitted form on shoe too give balance in back n legs.  Only ones,,, high priced,,, yes,,,, but also can get on sale,,,, k mart has them all time... But,,, go into a regular shoe store,,, find the correct size n width... That was alot of my problem. Then too find that my width has to be special ordered new balance is only shoe that does make that size so far that I know. yes,, ankle is weird,,,,, really weird one..  Not know how too explain the difference in neither. garuantee,,,, it not comfortable,,, when swollen,,, n foot swollen also  having too walk n wear shoes all day... That swelling is down n lost less wearing proper shoes all day ... being able too lift foot n keep up above tailbone level  in recliner n in bed both.. Helps greatly.... heheeee,,,,, have too get new shoes n prostethesis in shoes now cause of all the weight loss n new sizing in foot... Nice to have happen that is for sure...  Width has not changed much at all tho.. MS n RSD all affected mine... Hope that this encourages you to get this checked out.. And taken care of.. Feet are carrying alot of impact n weight in them... We loose we loose alot when feet not cared for... Huggzzz  dear,,,,  Annie
