Over the last few week, every couple of weeks or so I will feel woozy, dizzy, nausea, shaky....I dont know like I have the flu. I will run a low grade fever..99.5-100. My husband is starting to worry and says I need to document. I am just not feeling well at all. I thought eating would help, and it didnt, tylenol does well for fever but nothing else. I have foggy brain. Also, 2 weeks ago while sitting at my desk working Im sure it had to be anxiety I started to feel like my heart was racing and I couldnt get enough air even if I took huge breaths. what could be going on.... Im over feeling like Im sick all the time.
