ESA question

Hi
I have been on ESA for 13 weeks now, I broke my ankle,I have been to a interview with atos the day before my plaster was removed.
They said they would contact within two weeks and they hav'nt, I would like to return to work but my ankle swells up a lot when I am on it, I do a job which I am on my feet all the time, so was thinking of doing less hours for now so would probably earn around £50 a week,is it right I can still claim it till I can work the hours I used to.

Thanks for any replies
