High CRP levels do not typically cause specific symptoms on their own. CRP is a marker of inflammation, and symptoms are more likely to be related to the underlying cause of inflammation rather than the CRP levels themselves. Symptoms may vary depending on the underlying condition and can include fever, pain, swelling, fatigue, and other signs of inflammation. However, it is important to note that some individuals with high CRP levels may not exhibit any noticeable symptoms. Proper evaluation and diagnosis by a healthcare professional are essential to determine the cause of high CRP and address any associated symptoms.
