Sorry to hear of your back pain. Back pain can certainly disrupt all of one's day-to-day activities. The scenario your describe, along with your negative tests indicate that this is not an STD-related problem. While STDs can rarely cause back pain (very rarely) this is a more chronic problem which follows chlamydial infections. Nothing in your history suggests this is the case.
I suspect that the occurrence of your back pain and your CSW exposure are coincidence and nothing more. EWH
If you have an STD, it is most likely that it would be symptomatic but any STD can also be asymptomatic.
Once a person has HV, they typically have it for life. Some chlamydial and some gonococcal infections do cure themselves but it is not recommended for a person to try to "wait things out". Too much risk of complication or tranmission to others.
From the tone of your follow-up question, I beleive I have addressed your question. Please no more general questions which can be answered with quick searches. eWH
Thanks for your feedback and providing advice during this tough time!
Congratualtions on telling your partner. AS difficult as I'm sure it was, it was the right thing to do. I also concur that since you have not had sex with your parnter for 5-6 months, she is not at risk, had you contracted an STD during your encounter in June. She therefore would not need treatment.
It really is time for this threat to end. I have little more to offer you. No frther questions please. EWH
