This is likely to be chronic yeast infection. Some women experience chronic recurrent vulvovaginitis, which often require long-term or prophylactic oral azole therapy for control. So for that, the recommended regimen is fluconazole 150 mg every other day for 3 doses, followed by weekly fluconazole 150-200 mg for 2-3 months. This regimen abate the symptoms and prevents further recurrence in majority of women.
Boric acid wash for vagina can be used in resistant cases, as an alternative measure with the consultation of your physician. A specific culture; Nickerson or Sabouraud mediums should be performed in refractory or recurrent cases of vaginal candidiasis to confirm the infection. So you can talk to your doctor to get this culture before you start the treatment.
Women who do not improve with above can use, clotrimazole 500 mg vaginal suppositories administered once per week for six months which is also effective.
Also avoid (if you do) following;
1) panty liners,
3) sexual lubricants
The other possibility to consider would be "desquamative vaginitis" which is not due to infection. It is due to chemical hypersensitivity to the repeated vaginal medicines, which, after all, are chemicals. Following treatment would help you;
1) Get a refillable script for Acigel vaginal cream with applicator. Begin with 1/2 applicator at bedtime every other night for two weeks.
2) Then increase to a full applicator every other night for two weeks.
4) You can help restore the normal bowel flora by eating live bacterial culture yogurt every day for a few weeks and take acidophilus tablets three times a day for one month.
4) You do not have to use the Acigel while menstruating. Do not use tampons until the treatments end.
5) Wear loose, all cotton underwear as they absorbs body moisture.
5) Wipe front to back when you urinate or have a bowel movement. Bowel bacteria can infect vagina.
7) Do not shave the vulvar area as the pubic hair protects against chemicals making contact with the skin.
8) Avoid all chemicals in the Vulvo vaginal area.9) Avoid pantyhose and tight pants such as jeans which trap moisture near in the perineum 10) After exercise or any sweat producing activity, bathing or swimming, make sure the perineum is air dried., Moist surfaces that rub against each other break down and provide an area for yeast secondary growth ,
11) Follow a low carbohydrate diet. Take steroids, antibiotics and oral contraceptives only if very necessary.
