My platelets range from 850,000 to over a million. My red cells are also high, going up to 46.5 if I don't have a phlebotomy once in a while (every few months). White cells are only slightly and insignificantly high.

Eddie, your platelets are in what is considered a normal range. If they go up to 450, then you can ask about testing to see if there is a reason other than
inflammation. A standard CBC blood test should do the trick.

My platelets were listed as High when they were at 450,000 every test for two
years. I asked why, and was told it was Essential Thrombocythemia. This
was changed to Polycythemia Vera when red cells also started to rise.

A few people have symptoms even at your level, if they have ET or PV, but
it is more likely the numbness is due to...what was that again?....MS?

But I know by now that I and most docs are ignorant in many ways. Have
a blood test and ask what your platelet level means, and go to a hematologist if you want a more closely focused answer. EVen hemos disagree about what is normal, so expect the same difference of opinion one finds among neurologists.
