Is 99.1 a low grade fever?
Yes. High grade fever is considered to be anything more than 101 F.
So I do have a fever?
Yes. Normal body temperature is considered to be 98.6 F. So technically, 99.1 F is low grade fever. However this much rise in temperature can be there under normal circumstances as after an exertion or in very hot weather.
Can severe anxiety cause that?
Yes it can happen. There are two systems in our body working in a balance. These are the sympathetic and the parasympathetic systems. When we are in state of anxiety the sympathetic system is activated resulting in a rise in temperature and preparing the body for "fight" or flight".
Well my throat feels irritated and nose congested. I feel nauseous and have loss of appetite and energy. I'am suspecting an HIV infection. My 12 week 4 days blood antibody test came back negative but I don't know what I'm gonna do with the anxiety of waiting until the 6 month mark. Any suggestions?
