They are symptoms of hiv, but i have had those same symptoms many many times and i have had many hiv tests - all negative. Noone on here can reassure you, im in the same position as you thinking i have MS, not even my own doctor can reassure me. The only thing that will put your mind at rest is a HIV test, and if it is positive (which it WON'T be) you can deal with it. And when you get your negative result you can put all of this worry behind you, the chance of you having a crazy doctor who wanted to contaminate you with HIV is... Probably 0%. I have had the hiv fear SO many times, i swear down i know exactly how you are feeling and you know what im saying is right but at the same time that voice in your head is saying 'but what if...'.
Go get the test. You'll be ok you'll see :)
