Hello, I would be happy to assist you.
You can still have a yeast infection even though you do not have any internal symptoms. Certainly, the burning on the outside is most likely due to yeast as long as you don't have any lesions/bumps. I recommend you purchase a anti yeast "combination pack" like Monistat or Gyne-Lotrimin. The "combination packs" will have the vaginal insertion tubes as well as a separate tube of cream to apply to external areas where you have symptoms twice per day for 7 days.
If you develop lesions/bumps, your symptoms can be due to herpes and you will need to see a doctor for prescription medication.
I wish you the best. If you have additional questions, please ask. If none, please click "Accept." Thank you.
Yes, most likely.
make sure you get the "combination pack" and use the cream twice per day for 7 days externally. The vaginal insert you can use for 3 days if you get the 3 day kit
If you have been sexually active without condoms, you should see a doctor.
Otherwise, you can treat on your own and see your doctor if your symptoms persist.
