For the past week, I have been aching all over and feeling very tired. I thought I was just run down, but then 4 day's ago I started running fever. Fever is staying very low. Aches and pains are worse in the lower right pelvic area. This usually happens a day or so before I start my period. Doc doesn't know why. Suggested I take Motrin. It helps, but this continues and now seems to be progressing. I am not on my period, nor anywhere near my peroid this time.
