In UK Clinics don't do the swab anymore, think it was putting people off going, changed years ago, it's urine test now and antibiotics if symptoms. Clinics in Pattaya wouldn't do the old school swab test.l
In Pattaya they rarely bother testing, they treat the symptoms. Testing is far more expensive than the actual treatment, usually it works, occasionally not. Even back home they would treat it with antibiotics before getting test results
Depending what you got Doxycycline also very effective and cheapest. Don't forget Ceftriaxone injection is the recommended treatment with Azithromycin for Gonorrhea\ Chlamydia
People often moan that Walking st drink prices are way higher than LK Metro for example. The agogos i go to in WS are 50, 55, 90, 95 baht for draft. I don't bar fine from there anymore as I don't need to, but I don't blame the tourists
