Hi, welcome to the forum, the symptoms you are going through can be due to hormonal changes or imbalance. Estrogen deficiency can cause vaginal dryness and itching. The other causes can be due to irritants, vulvovaginitis due to candida albicans or Trichomonas vaginalis.
In such cases vaginal smear, wet mount and culture will aid in diagnosis. You may need to take appropriate antibiotics, if infection is suspected. Maintain absolute cleanliness (you and your partner) like proper washing of hands. Symptoms will subside soon, if not consult gynecologist. Take care and regards.
Try Dr. Coca's Pulse Test. Search for free download. It should help you determine if red meet is the problem. Meanwhile for a couple days you should stay away from from red meat.
Vaginal itching and tingling. You knows. Maybe it is not related to the same cause.
Is the anything else that may point towards a yeast infection? Just a thought.
The above test might shed some light if you also show a sensitivity to sweets and carbs and a whole bunch of food items that "feed" the possible yeast issue.
To do the test requires some patience. It is a week long, but you do get an indication when something is reactive, within a short time.
Hope this helps,
Blessings
