Detailed Answer:
Greetings.
so now the problem has become chronic.
here it can be two possibilities.
either there's an allergen. so we need to find that out. Try to be more observant about it. any food,fragrance,season,any particular soap etc.
Also we will boost the immunity. we will add certain items in the diet like probiotic milk and lot of anti oxidants. along with this I highly recommend you to give vitamin c supplements. as this improves the immunity.
Along with this give one full course of cervix one for five days to get immediate relief.
hope this helps.
let me know if you have any queries.
