Clearly you had urethritis. You don't say whether or not you were tested for gonorrhea or chlamydia; you should have been. It could have been either one, and your doc treated you for both gonorrhea and chlamydia. But of all cases of urethritis, most are nongonococcal urethritis (NGU), ie not gonorrhea. Off all NGU, chlamydia is the most common cause, but still is responsible for only 25-40% of cases. About 10-20% are due to Mycoplasma genitalium. Trichomonas is the cause of 1-5% of cases. The cause is unknown almost half of all cases of NGU.
If your doc didn't test you for chlamydia (or gonorrhea), you will never know whether or not you had them. However, the fact that your symptoms did not improve at all does favor trich as the main problem from the start. All the other causes would have cleared up (or at least the symptoms would have markedly improved) with the treatment you were given.
I never heard of Alinia (generic name nitazoxanide) until your question, but I looked it up. Interesting you were treated with it. On a quick search, I find it has been found to be active against trich, but there is no published research (in English) showing that its effectiveness has ever been studied, and it is not approved by the US Food and Drug Administration for treatment of trichomoniasis. That doesn't mean it won't work, but I wouldn't have a clue what dose to use or for how long. But your doc may know more about it than I do. The usual treatments for trichomoniasis are metronidazole (Flagyl and other brands) and tinidazole (Tindamax). But you're obviously improving, so hang in there.
The final mystery is where and when you were infected. Trich can be carried for months, perhaps years. I would be somewhat surprised if you were infected during attempted intercourse without successful penetration. If the event you describe is your only sexual exposure in recent weeks, it's a good bet; but conceivably there are other partners who need to be notified and treated. At a minimum you need to tell your friend that she probably is infected.
When trich is found in women in "rest homes", it is either the result of chronic infection, acquired many years previously; or of recent sex, possibly sexual abuse. Trich is not acquired except sexually.
Thanks for sharing your story. I learned from it. Best wishes-- HHH, MD
He did not test me for chlamydia he said I had urethritis and assumed it was chlamydia thus the treatment for chlamydia and gono. So you don't suspect trich and the treatment would have cured chlamydia or gono.
You misunderstood. I think the diagnosis of trichomoniasis probably was accurate. Your doc probably observed the organism in your urine (there is no other way to diagnose trich within an hour) and you are improving on the Alinia, which would not be effective against most other causes of urethritis. Your previous treatment (levofloxacin plus azithromycin) would have cured gonorrhea and/or chlamydia if you had them; but you probably didn't anyway. I suspect you had trich, and only trich, all along.
