Hello,Your symptoms suggest a sinus infection. The permanent feeling of pressure behind the bridge of the nose is likely due to sinus . If you have not seen an ENT doctor then you can consult one. You can have a scan of the sinuses also.Hope this information will help you. Wish your early recovery. Any query, please ask. Regards.
I have already had antibiotics for this and no indication from a blood test that any infection is present. I also am sure that this is not the case.
Have you heard of similar cases and their conclusions?
