You are an MD? I recently expire need sexual trauma. That was in feb. I got tested for all STDs two weeks, or so... After trauma happened. Tests came back negative. Two Dr. (My family doctor, and an emergency room MD) told me not to worry about STDs. Late yesterday after noon I started to experience a slight burning sensation at the end of urination, and then this afternoon the slight burning sensation was accompanied by pink on toliet paper after I wipe. Please console me. I feel soo freaked out. I went to the walk in clinic after work, but they are closed. What is going on? Thank you so much for your help!
