Hi Karen Lou, if i where you i would not push harder! It is very normal to have pain and setbacks after you just have been FWB, you might harm something if you push to much. I had tremendous pains in my foot and ankle the first week FWB and went a few days from using 1 crutch to 2, then my body could find the proper balance. We should not forget that our bodies are working really hard to heal, don’t overdo it,
Best of luck
