I am new PsA diagnosis. It took 10yrs. About 4 months ago. I developed extreme pain in the heels of my feet. I was working, after starting Methotrexate 6weeks, (failed). Then next plaguing (sorry spelled wrong-also failed). The pain has become so much worse. I can barely walk and when I do its extremely painful. I am waiting on Humira, but I was wondering is my mobility issue is permanent or will treatment help with this and pain.
