I have a dark bruise like mark or rash which is about two inches across and circular on my upper left thigh which has been there for about a week. The rash/mark does not itch or hurt. I have had low grade fever which comes and goes in stretches of several hours throughout the day. For the past six days I have has stretches of time (several hours each time) of intense sweats which leave my bed soaked. In the first few days I would go through a stretch of time (perhaps a couple hours in length) of severe chills but I do not experience these anymore. I am tired and my head is sensitive to touch. I have some nassua (sp) but no vomiting. Slightly loose stools.
