See the replies in your other thread; no point in two discussions. But I'm glad to see you're seeing an ID specialist.
Oops, my mistake! You had a comment in another thread and thought you had been the primary questioner there as well is here. Sorry for any confusion.
If you had no symptoms at the time your syphilis was diagnosed, don't worry. Most cases cause no serious health problems for many years. You'll need several blood tests over the next couple of years, but if those show a good response to treatment, all will be well. Your ID specialist probably will tell you pretty much the same thing.
