Fever
Another give-out sign that there’s an infection going on is having a sudden rise in body temperature. Fever is always a sign of infection or inflammation, and it is likely to be present if you have an abscess. Waiting for too long and neglecting your condition might even make the problem worse, and your fever will keep on rising. Be careful because fever is not a local sign of inflammation but a systemic symptom. Thus, if your starting to feel a change in your temperature, it is highly likely that the infection is starting to spread to nearby tissues.
