Hi Welcome to Healthcare Magic,
Burning sensation in the urine passage area is a very common problem in females .
The reason for the same are - 1) Local candidial infection for which u can take an antifungal ointment for local application. 2 ) Urinary tract Infection
can also cause such complaints , so get a urine examination done to rule it out. 3) At times when u r dehydrated then u can also have such sensation .
So as your symptoms goes , doesnt seem something serious rather you need a gynaecological consultation and go about with the right treatment.
Thank you , hope it was helpful.
