At least you've been given medication for it. I have asthma which is mostly under control but sometimes chronic and a few years ago I had constant pain in my chest and my doctor told me to rest and drink orange juice. Incidently, my boyfriend at the time was a little bit ill and his doctor gave him antibiotics straight away. So a few nights later after coughing for several hours on end I ended up at hospital in the middle of the night, diagnosed with a severe chest infection, had to be nebulised and put on steroids for a fornight. It was three months before I was finally clear of that infection and all I have to do it sniff now and my doctor puts me back on the steroids straight away, I think he learnt his lesson there!! Sorry to hear you're not well, though at least it's not aids.
