My CRP is high. ESR is 15. Problem?

Dear Doctor, I checked my blood CRP. I saw it is 14 high, whereas ESR is low 15. I don't know why CRP is High? I have High BP. I have Asthma and urticaria. I am taking medicine for above 3 health problems. I am very obese 113kg, height 169 cm. Age 39. My ankle, knee joints are paining but not swollen. I have High calcium hence it led excess growth of bones in my  joints, I was operated at the age of 12. I am normal now. I did Master health check up in May 2017 Lab report was fine then. I don't have Diabetes. I have stomach burning sensation on eating spicy food, and pain in knees, ankle, neck and arm joints. My 2 elder sisters have autoimmune SLE and Rhumatoid. I don't know what is my problem? Please advise what test I have to do further so as to know the exact health problem or reason for inflammation. Is it heart problem or beginning any serious health problem?
