Receiving oral sex puts you at risk for genital herpes type 1 (if you don't already have oral herpes type 1), syphilis, gonorrhea, chlamydia and NGU.
If you got syphilis from oral sex, the chancre would be on your penis, not your back. I don't know what the sore on your back was, but the chancre appears at the point of infection. Still, syphilis is easily diagnosed with a simple blood test, so just go test.
Syphilis eye involvement can occur as early as 4 weeks, but can take longer. Just go get tested.
I don't know a lot about MCTD, but if that makes you immunocompromised, you should definitely be using condoms for oral sex.
