Hi
The symptoms you describe are not commonly associated with herpes or syphilis. In fact, most people who get herpes or syphilis do not develop any symptoms.
If you did have signs of herpes the most common symptom would be painful sores; the most symptoms of syphilis are a painless sore and a rash on the trunk, palms and soles of the feet.
Given your concern about STIs it is probably a good idea to go for testing. You can get an STI test at any doctors office, or you can check out our clinic finder if you need help finding a clinic to go to for testing.
