First of all foul smelling vaginal discharge
and partial seizure
are not related to each other So i would suggest to consult another doctor for that and change your medication if necessory. Yellowish foul smelling vaginal discharge is suggestive of trichomonas vaginalis
.. it is infectious condition . Treatment for the same condition is cotrimazole. And your history suggest you might be having urethral fistula because you have vaginal discharge on straining condition..so i woud suggest you to consult gynecologist and have some investigation for both condition and then start treatment accordingly..
