Hi Louisa- according to my little blue book where I record all my blood tests, the acceptable ranges for CRP are 0-5 mg/l
As Lizzie says the ESR is non-specific test for inflammation and so is not used as a key indicator at my clinic. Sorry this doesn't help much
In the early stages of getting your meds sorted it is a real juggling act as they will be trying to balance getting the best possible outcome which takes up to 3 months to become clear, versus side effects which each individual may or may not experience. If you feel better, then that is a crucial part of the process and it sometimes helps to keep a diary so you know how you currently compare with say a month or two back. I have a little book issued by my hospital so I can record all my results, and it really does help to make sense of it all.
Sorry I can't help more, but hang on in there and see how it progresses - it's still early days for you and things seem to be generally getting better so that's great - Sylvia xxx
