Hello and thank you for your question.
The results of your blood work is not very specific and does not point to any specific condition other then to some inflammation as evidence by mildly elevated CRP. However, CRP is a very non-specific inflammatory marker and doesn't rule in or rule out any conditions.
Your blood results, however, did rule out several other conditions which could have been responsible for your symptoms such as rheumatoid arthritis, liver disease, and anemia.
I would recommend repeating your blood counts in 2 weeks to check for any changes.

It sounds that your symptoms were brought on by a viral syndrome which has attacked your muscles causing generalized pain, inflammation and neck stiffness.
We worry about neck stiffness when we are considering meningitis (inflammation in the brain), however, there are usually headaches, fever, and some kind of abnormality of your white counts (elevated, not low).
If your symptoms persist, you will need further investigation. I would recommend seeing a rheumatologist who specifically specialize in muscle disorders/inflammation.
Hope this helps. Let me know if you have other questions. I am here to help.
