I'm a 30 year old female. For a couple of weeks now I haven't really been feeling well. It started with a back ache and now everything hurts. Kind of like with a fever but I don't have a fever. I also have been very tired. And I have swollen glands. I thought I was getting the flu but no fever, runny nose, sore throut, etc. I'm really not that sick just not feeling well. I don't know if I want to run right to the doctor because,like I said, I don't feel sick. Any help would be great. Thank you.
