Hello madam, multiple ankle injuries can give rise to ligament outs instabilities which may recur. Regarding your pain on other sites may be due to increased pressure on these sites due to injury
at ankle. Chronic ankle sprain
also give rise to ankle arthritis
. The slip must have caused some injury inside inside which is causing pain. I advise you to continue the brace and go for investigation like MRI
which will help you to know the full status of ankle joint and might help to diagnose why you have frequent inversion injuries.
