No dear my frank opinion is that you must be having some kind of viral or fungal infection which might have become chronic so it should not be neglected. It is advisable not to try to treat it by home remedies which may supress the feeling of itching & burning temporarily but would not clear the cause. You must undergo gynecological examination & may also require the culture & sensitivity examination of vaginal secreation if any. As continouing irritation of th vagina may lead to serious probles later ( cell hyperplasia may lead to atypia & further to cancerous conditions ). So it is better to treat this condition earliest. The exact cause can only be given after visual & per vaginal examination so it is advisable to have gynecological opinion.
