I have had this feeling for 4 days now of wanting to defecate all the time, which usually gets worse after a meal or snack and I have to actually go to defecate so as to reduce the pressure. I am 25 yrs old and became sexually active febuary of last year. has had two sexual partners, candidiasis, gonorrhea and PID that reoccured once. I once ahd this back and stomach pain after the reoccured PID had been treated, but the doctor said I am okey. what is wrong with me?
