Hi. I ve hit a block with diagnosis of a problem I believe is related to sinus. I have had previous chronic sinusitis and have had a FES operation. From time to time historically I ve developed symptoms of head congestion, and lethargy and have usually had antibiotics and it has come right. This time however, the symptoms have not abated. I ve had NSAIDs, and two courses of antibiotics. I have had radiology which showed chronic sinusitis including polyps, but my specialist who also examined my sinus with a scope, says there is no sinusitis ,he s doesn t believe surgery is warranted. Meanwhile Im left with the symptoms for over six months now of sinus type headaches constantly,and feeling of congested head,and a feeling of lethargy. I m getting ting quite desperate. Keen for your opinion
