Haematologist appointment and bone marrow biopsy

Hi , 

Had my second Hametologist appointment today, bloods taken and my results from my last visit.

Bloods still showing high platelets so I'm having a bone marrow biopsy in the New Year . 
Also having a scan as kidney stones may be present, so could be the reason why my count is high ? 
All other results came back ok so far . 

Has anyone had this procedure and can reassure me . 
 

I hope everyone who's had appointments today and tomorrow are doing ok .
