After seeing an Oncologist due to slightly high RBC on the high side. He told me to start taking Baby Aspirin when I left his office. The hospital performed Spleen and Blood Gas and all is good. Seen the doctor 3 weeks later to informed me of the findings. When I saw him the following week I came down with Vertigo. Blood were drawn to check my RBC. It is the same and performed a Phlebotomy. A week has past and still not 100%. Could the Aspirin cause the Vertigo?
