Hello, Doctor(s). I am 24 years old and I am having these weird feelings these past few weeks and they are worrying me. Two weeks ago I started feeling chest pains and shortness of breaths and burning sensation in my abdominal area. I feel like my heart is inflated. My joints ache and my lymph nodes seem to have swollen. Yesternight I sweat all night long, but I think it is because the heat in the room was too much. Today I felt feverous. Would you happen to know what is going on? I have been thinking about 2 things that may be the cause to this, but I am not sure: 1: Few months I broke up with boyfriend whom I suspected to be an HIV carrier. We had oral sex and kissing (exchange of spit). 2: Last month, I stayed with my sister and her baby, but then they were infected by the flu and I had to get masks at the hospital for me not to get infected. But one day, when I had just got one mask from the hospital and put it on, I felt very weird, a little headache and very unusual feeling. Plus the mask looked like it had just been used and put back into the box. I know this may sound weird, but I just want to know what is going on and if there might be something I should do ASAP to get my health back. Thanks.
