Hi welcome to Health care magic forum. Diflucon has nothing to do with the symptoms you are facing, some times occur with little effect. for that you can use anti ulcerants with your doctors advise.
Migranal drops will have many side effects like hives
, difficulty breathing
, nausia, swating etc, First stop deflucon drops and when you feel free of the symptoms you can take , deflucon.
From your quiry it is learnt, that you are suffering with cold
, not much head ache, migranal is more use full for migraine headaches
, but not for cold headaches. so confirm this first.
For yeast infection you should get at least 50% relief by this time, no relief means you may have another alternative medicines, confirm with your doctor.
Wishing for a quick recovery and thanks for calling.
