High sed rare of 67. It's been climbing  for months. Any ideas what I investigate or ask my doc to investigate. At first it was complicated cuz think my family doc thought my MS doc was looking after it but that's not the case; my MS doc just so happens to do monthly blood work and that's on there but copies are sent to family doc. Now my MS told me to tell my family doc to investigate, I'm just curious what is it that possibly should be looked into?
