Insidious flu. By neuropathologist opinion.

 A good feeling to the ending a first week of a  disease is a not meaning about a full recovering.

And on the fourth day of flu in Viktor ,temperature stayed normal, but doctor added still three days to stay at home, and on these days, he sure ,that they are free and he can use skates. And in 2 days he had headache, dizziness, and a time to work going, he stayed at home for a month. Headaches  and for future still kept and added nausea, and in a few years, he could not fight from periodical attacks of headaches. A flu is insidious disease , than  other disease, such infection gives different and hard complications damaging for nerve system, and many patients forgetting ,that flu is not a cold, cough and high temperature. Flu virus enters in cells for a surface of breath layers ways ,  as staying in these cells, destroying theirs activity. Poisoning substances are toxins forming of active spreading of viruses and dead of cells, causing  organism poisoning is intoxication. Virus affecting on the regions for nerve system. And here is chill, weak common, ache joints, eyes hurt, that means flu infection damaging vegetative region of nerve system, thus  this region regulates function for all organs, organism  systems and giving relationships with external environment. Under impacting  toxins a wall  of vessels head brain on separated regions are necrosing or destroying, that is reason for many haemorrhages in substances for head brain or under brain membranes. And patient having sense wrong, cramps, paralyses for different localization. And a most spreading complication after fly is arachnoids, disease calling as conditional.As a net membrane of brain is arachnoids not having vessels and inflammation here is not must be having , thus any inflamed process is not limiting just any membrane.  And usually, when we are shares arachnoids  , thus inflamed of brain membranes meaning. As ,like a meningitis, but limited, and not having such expression, so as pus meningitis involving in process all membranes for head brain as for all his extension. Origin arachnoids  are  different having, as \infection, injuring, reactive, as about an inflamed process, that  is of entering in brain membranes  bacterial infection from a pus niduses in sinusitis  or otitis. And on the place inflamed on a limited part of space are brain membranes ,like sticky, but if inflammation taking all theirs parts are more, thus a forming a few these niduses, and separated parts of membranes ability detaching, forming cavities,like  cysts, filling with a spine-brain liquid is liquor, such niduses keeping sticky for a long time, and symptoms  in patient finding constantly. A sticky process lead to destroying circulation for liquor along membranes a brain, and destroying his sucking in venous net, that of closing a part of  brains membranes,thus in other diseases as in flu, when a loading on vessel system staying big, destroying  circulation for a spine-brain liquid is increasing.And result from these is rising and sometimes lowering pressure of spine-brain liquid, and here are reinforcement symptoms raws  as headaches, dizziness, nauseas, weakness. And arachnoids here is of activating under affecting viruses of bacterial infection, obvious of  till a time keeping a hide. Timely curing chronic nose diseases, teeth, throat, ears, is an effective preventing for flu complications. And meeting is often, that who enduring flu on legs ,that not staying at home, or not curing by doctor s advices. Such patients harmful for  yourself ,and for surrounds, as spreading infection. A take care ,who before endured meningitis, arachnoids or encephalitis, that for those, flu  is very dangerous . These patients on epidemic time needing right away adding preventing methods, as using anti flu vaccination, or use remantadine , less starting in places with many peoples, use  private hygiene. And remember, that  lowering temperature, good feeling ,and seems restoring work capacity as to the ending first week having ,is not meaning about a full recovering.Just your doctor will decide when you must to  visit work.
