Hi ! Thank you for your query. Dear chris, Looking into your problem it seems that you may be suffering from chronic fatigue syndrome since you do not mention any other complaints. it is a condition where the person experiences extreme fatigue , muscle pains etc which are not relieved by rest . it is a very debilitating disorder . well diagnosing this is a difficult task and mainly it is a diagnosis of exclusion. treatment options are cognitive behavioral therapy and graded exercise therapy etc. I think you should consult a physician for this and get yourself evaluated for same .Regarding antiviral therapy has been tried with mixed results but still not very valuable option. Hope you are satisfied with the answer. If you have any further queries feel free to ask. Wish you good health. Take care. Dr. Shruti
