Even if your brothel partner had HIV, and even if you hadn't used a condom, the chance you would have caught HIV would have been somewhere around 1 in 2,000. Add those odds to the brothel's testing policy and reported history of no HIV transmissions, plus the condom use, and nothing else in your question matters. The amount of possible body fluid exposure that could have occurred, based on your description, almost certainly is not sufficient to transmit HIV, even if your partner had the virus.
Symptoms almost never are useful in judging new HIV infections. That's because even the classical symptoms of new HIV infection usually are due to other things, since many viruses and other medical conditions cause exactly the same symptoms. And submandibular lymphadenopathy -- if indeed you have it (it seems your doctor is unsure) is much more commonly due to a variety of viruses other than HIV. And you don't mention fever, which almost always is present in acute HIV infection.
So my advice is to just wait for the HIV test, without a lot of worry about it. You can expect a negative result. Then you can work with your doctor on other possible explanations for your symptoms. Most likely it is nothing serious.
