I tried working part time a couple years after my SSD started. I managed to last nine months. When my review came up, they asked me about my working, and why I wasn't anymore. I told them I gave working a try and my body didn't like it. I told them it set me back healthwise, and my doctor wrote a letter confirming it. They continued my disability payments.
If you continue to work, it probably would hurt your chances. My advice, if it's creating that much havic with your body, then you should quit and have your rheumy make a note of it. It's not worth the extra income if your killing yourself to get it.
