I felt so weak today and my body just completely shut down . Hubby took me to my PCP and I had a fever of 100.3 . She advised I take some Tylenol , rest and drink lots of water which I did . So now my temp is a lil elevated at 99.0 .. I wish I knew where this fever came from. I don’t have a cold or anything . I just wanna feel like myself again .
