Conditions

Trichomoniasis

Is it normal to be scared of the doctor? Vote now! >

Like all sexually transmitted infections, trichomoniasis is relatively common and is usually spread by having unprotected sex. It affects both men and women, with symptoms tending to appear 5 to 28 days after exposure to the infection. However, men very rarely present any symptoms when they are infected, and approximately 50% of women present no symptoms at all. But if symptoms do appear, then women can look forward to soreness, inflammation and itching around the vagina; a fishy-smelling discharge that may appear thicker, thinner, frothy or yellow or green in colour; pain or discomfort when passing urine; discomfort during sexual intercourse; and pain in the lower abdomen. Men can also experience pain after urination and ejaculation; thin white discharge from the penis; and similar discomfort during sexual intercourse. Trichomoniasis is usually treated quickly and easily with an antibiotic that, if taken correctly, is at least 95% effective. But let’s be honest, it’s probably easier to just wear a condom.

I have been going to my doctors on and off for years thinking I kept having thrush and bacterial vaginosis. About 6 years ago I was treated for both these and the doctor prescribed me a pessary for 6 months to use after my period. They helped but the problem never went away. I just used panty liners and have just gotten on with it as I felt all these years it was thrush. Went to doctors recently and was informed not thrush so what is going on?? Only other symptoms I have read are similar is trichomoniasis. Would I have had this for 8years I have been with the same partner..

Well everyday for months now I get quite a bit of discharge in my knickers, it never did smell but now it is starting to smell everyday and I don't know what to do?? I don't want to talk to anyone as I'm only 15 and it's quite embarrassing. The discharge can sometimes be thick and other times it can be quite watery. The smell is really uncomfortable and embarrasing however I cannot explain what it smells like (it's not a fishy smell). I Have had unprotected sex a few times and i don't know if this is the cause of it? I'm clean haha, I shower everyday? I really need help😩

For a month now my skin is red and is slightly tender to touch on my labia majora (The outer lips where the pubic hair is) there is no soreness or redness around the opening to my vagina, however it does feel more sensitive than usual and more moist, I get tiny amounts of clear/white discharge which has no strong oder but maybe slightly acidic smelling if anything - the discharge can be very itchy. I've been tested for thrush and bacterial infection and both were negative. I've also had a full GUM test since the last time I was sexually active (Aids, Gonorrhoea, Chylamidia, Syphilis) and I don't have any of those either. Could I have this?
