<s>[INST] I m 36 male who regularly uses meth intravenously. I m having lower back pain and sever testicular swelling and pain. I have looked stuff up and I have many symptoms of Epididymitis. Could this be caused by my use? Is this passable through sex? Do I need to go to the doctor? [/INST] HIWell come to HMCThis may not be because of using of narcotic drugs but such drug are not good for health because this may aggravate the symptoms and may lengthen the course of disease, here the chances of infection is very likely and this need to be ruled out, take care. </s>
