Please help I have been dealing with this issue for 5 months now. I had a new sex partner and a few weeks noticed a funny itch and discharge. I went to the doctor and all my test came back negative for STD's.However the doctor said i had strep or bacteria in my urine, so I was prescribed 500 mg of penicillin one tablet 3 times a day.T his was 6/23/12. This didnt help so I went back to the doctor in July and was positive for urinary tract infection and 8/12/2012 was then given 500 mg of metronidazole one tablet twice a day for seven days.This still didnt cure me,, mind u everytime i go back to the doc .. im checked again and I am still positive for trichomonas. next trip to doctor was 9/22/2012 i was given 150 mg of clindamycin two capsules twice a day for 7 days. This did not cure me either. next doctor visit was 10/06/2012 doctor said i needed a longer treatment so i was given 250 mg of metronidazole and azithromycin for ten days .. this didnt cure me either 10/13/2012 i was given. and doxycycline. this didnt work either.. so i just went again 11/10/2012 and was given tindamax 500 mg 4 pills for single dose. im still not cured. why arent any of these antibiotics working what can i do? my doc said in two weeks i shoul get a referral in the mail to a gynecologist. but what more can they do.. what other treatment is available? Is trich that hard to cure.. im so depressed
