I have found 2 papers that may be relevant to your question -
This paper probably answers your question the most - I have only schemed through it, and it seems that the results were insignificant. You can check out the paper in more detail, hopefully it will get you to more resources that can help with your research.
I have also found this paper which does not entirely answer your question, but I think will help with your insight.
Also keep in mind that some neuroimaging research on social exclusion in causing activation in regions (e.g. dACC) associated with physical pain employs reverse inference method. This does not mean the results are entirely unworthy of considering - just something to keep in mind when looking at neuroimaging result interpretations.
