Your symptoms do not seem to be STD related based on the fact that the medication taken would have cleared any bacterial infection.
Only advice I have to to seek a new Dr.
Can you guide me how to confirm that I dont have any STD.
Is urine culture enough to prove that. Do i need to do HSV antibody test
HSV...is herpes, you would have to post in that community for answers about herpes.
You can have the Dr do specific tests for STD's a urine culture will not look for STD infections.
Today I did Sonography and the results are everthing is ok except "urinary bladder is thick walled"
