Ouch that sounds painful. Have you tried changing to softer soled shoes and adding gel inserts? Maybe orthotics would help? I have terrible feet as well, and enbrel helped a ton while I was on it. Prednisone and celebrex helped a little in the past. Have you tried icing your feet a few times a day? Trying to think of other things that have helped in the past. I really, really feel for you! Big hugs
