Woke up switch swollen lymphnodes in groin and a swollen testical. Dr ran tests and gave me antibiotics. Swelling and lymphnodes went away. Fever persisted for 4 weeks. Infectious disease Dr tested for many things to no avail. Retested blood at 5 weeks most everything back to normal except platelets were high along with C-reactive proteins and my SED was extremely high. I have severe fatigue with joint/muscle pain headaches and eye strain. What could cause this. I have now been referred to a rheumatologist.
