I have been low energy for 5 months. I usually run 23/x wk. I was sick with walking pneumonia that turned into pleurisy. I have a normal BMI, 40 yr female, healths healthy, no smoking. I have had a sore throat now for 2 weeks. 1st week real bad, fever, body aches, took a whole week to get better I still have low grade fever and now stiff neck and very very thirsty. I have headaches often. I get sick all the time and very tired of it. I don t want to be poked and studied I just would like a path to pursue. I have a feeling my immune system week as I have 3 kids and none of them get sick like I do
