Hello. Even though your symptoms are vague and nonspecific, it s appropriate to be concerned about sexually transmitted infections in this situation. STIs don t always cause the textbook symptoms we ve all heard about: penile discharge, painful urination, testicular pain, etc. It isn t at all unusual for chlamydia, trichomoniasis, or even gonorrhea to cause a subclinical infection characterized by minimal or no symptoms at all. To put your concerns to rest, see your doctor or visit a public health clinic for STI screening. If you do have an STI, early treatment will forestall any complications and prevent transmission to your next partner. Good luck!
