Your physician is absolutely correct. If you had been infected with the Human Immunodeficiency Virus for 20 years without treatment, you wouldn't be here to ask this question. As HIV progresses to AIDS, one loses weight and becomes sicker and sicker with infections that most people are able to toss off with no problem, and they die of one of those infections.
While it is an excellent idea for anyone who is sexually active to get tested for STDs at least yearly unless they are in a mutually monogamous relationship, there is little chance that you've had HIV for 20 years and still lived to tell about it.
Have you seen an ENT (ear-nose-throat specialist physician) to determine what is wrong with your throat? There can be many different kinds of causes, including some not connected with the throat such as digestive problems like GERD (gastroesophageal reflux disease). Have you been tested to H. pylori (the bacteria responsible for ulcers and GERD)? It is a common cause of sore throat and coughing.
A urologist should be able to check out the testicular pain. Simple bacterial infections are the most common cause, and epididymitis is the most common diagnosis. This is something that is easily diagnosed and treated with antibiotics.
