How does bacteria cause pain?
in Health
I just got strep throat....again..... and I was just curious, why is it so painful if it's just some little microscopic bacteria?? How can something so small physically affect my entire throat? I know pain is built into us to let us know when something is wrong, injury, infection, etc. but is the pain from strep bacteria from my body telling me it's infected or is the bacteria itself causing pain by attacking/excretion/poison/etc??? same thing with any type of infection, it's always more painful when infected..... why?

JONATHAN,
BACTERIA CAUSE INFLAMMATION AND THIS IS WHAT CAUSES THE PAIN.
BACTERIA IN AND OF THEMSELVES DO VERY LITTLE , IF ANYTHING, BUT THEIR BY-PRODUCTS CAUSE DRASTIC CHANGES TO THE TISSUES THAT ARE INFECTED.
THE NERVES THAT ARE WITHIN THOSE TISSUES HAVE SEVERE REACTIONS TO THE CHEMICAL BY-PRODUCTS AND AS A RESULT YOU FEEL PAIN.
because when it's infected, it involves your body's immune response. Cell mediated response and vascular response will take place causing inflammation and your blood vessels to be more permeable causing swelling (edema). Your throat would also heat up and hurt as a result of this infection
