hi i had gone through your query and understand your concerns. i would come up with,the most possibilities to fit your condition .these include
high levels of CRP are caused by infections and in many chronic diseases.
the CRP test can't show the location of the inflammation,and what type type of inflammation causing it. further clinical evaluation of the case may needed.
1.first possibility is, RHEUMATOID ARTHRITIS; is auto immune disease and confirm with blood test
for RA factor,CRP,ASO trite,and ESR
2.second possibility;INFLAMMATORY BOWEL DISEASE;colonoscopy
may confirm the diagnosis besides increased CRP levels.
3.third possibility is,INCREASED RISK OF HEART ATTACK;inflammation can damage the inner lining of the arteries and make having a heart attack more likely.
I hope this is helpful for you, thank you
