Hi @stfocht and welcome to Mayo Clinic Connect. According to Testing.com, If an ESR is abnormally high, it means that the red blood cells fell faster than expected. This usually happens when the RBCs have more protein within them, which causes them to stick together. Many conditions can cause an ESR to become elevated." --- Erythrocyte Sedimentation Rate (ESR) - Testing.com: https://www.testing.com/tests/erythrocyte-sedimentation-rate-esr/
Have you talked to your doctor yet?
