Can I get fillers of any kind if I have Lupus or undifferentiated MCTD (mixed connective tissue disease)?

I went to a plastic surgeon for a cheek/eye fillers consult and he at first he told me that I could not get fillers because they increase the probability of an adverse allergic response to the filler (I have MCTD that my rheum though might be early stages of Lupus) but when I told him it's mild he said I could have them. I had lip filler in the past and had no adverse response. The surgeon who did those fillers said Lupus was not at all a problem. Would like clarity, thanks.
