In my experience, the "normal range" for those attributes is not necessarily accurate. It's also possible to have several different forms of auto-immune pain, inflammation, swelling etc. without necessarily having readings outside (or very far outside) the "normal range." They can even be quite severe, particularly arthralgias, without necessarily spiking your ESR or CP.
So, just because your symptoms may not match up with what is "expected" at a given reading, means next to nothing IMHO.
Conditions: Reactive Arthritis (AKA Reiter Syndrome), Crohn's Disease, Chronic Pelvic Inflammatory Syndrome, Sacroiliitis, Costochondritis, As Yet Unknown MS-Like Relapsing/Remitting Neuropathy, and a partridge in a pear tree.
Medications: Currently not that many are taken daily, but there are many at my disposal for part-time use. Low dose pain medication, after years at high doses. Working on innovative ways of taking lesser-known pharmaceuticals and non-prescription supplements to maximum benefit.
