This year I had for the first time the Flu jab. After that I had what I would call a bad cold and general lethargy . The fact is since then I have not felt fully well.Prior to this time I had been feeling the best I had felt I since being diagnosed with Hashimotos. .It feels as though I am fighting a virus. I have been to the Doctors who says it cannot be the flu jab. What do you think.
