why did they treat you guys for so many std's? did you test + for more than just trich?
there can be false positives for trich. at this point I'd just err on the side of caution and both you and your partner retreat for trich with the metronidzol and then repeat your testing again in a few weeks just to make sure it's gone.
I was given a shot of rocephin, 2 oral antibiotics each 500mg of metronidazol and 500mg of cipro took meds twice a day for 10 days he was given a shot, a single dose of the liquid med that you mix and 7 days of a pill taken twice a day and after treatment I think we still waited about a week before having sex again.. I know I haven't been with anyone else he says he hasn't but why would it return after 10 months?
trich usually is cleared up easily with proper treatment. what medication were you and your partner given? how long did you wait to have sex after treatment the first time?
