Inflammatory symptom: You are describing symptoms suggestive of chronic inflammation which may be due to infection, auto-immune disorder, neurologic or Allergies. What makes the symptoms better, what makes them worse? Do you have symptom-free periods and what triggers the symptoms? I would suggest you need allergy testing and you may try OTC antihistamines, if no improvement, your doctor may need to investigate cause.
