I had huge swelling in my labia and it was really painful. I visit to a doctor and she prescribed me some antibiotics. She said it may be the cyst. Then it will burst out in 3 days. I drained all the pus and i get a instant relief. She told me to do some test too but all the test reports were normal. And within 1 week it swelled again and start paining. I took the same dose of antibiotics that the doctor prescribed earlier and again its burst out. What is this and why its happening again and again? How to cure it permanently?
