Can you get a fever from pain?

Actually, pain itself doesn't cause a fever, but whatever is causing that pain—like an inflammation, tissue damage, or an infection—is what triggers the fever. Don't just treat the pain with painkillers; you need to identify the root cause.

I had a severe toothache last year that shot up my body temperature to 101. My doctor explained that acute inflammation causes the release of certain chemicals that raise body temp. Applying a cold compress to the painful area and consulting a specialist is the best way forward.

Please be very careful with this. I once ignored a severe back pain thinking the accompanying fever was just due to stress, but it turned out to be a deep internal kidney infection. If you have both pain and fever, please see a specialist immediately to avoid complications.

Do not rely on online forums to explain away a fever as just a 'reaction to pain'. Fever and pain together are classic signs of your body fighting something serious, like an infection. Go to a hospital and get a proper diagnosis from a qualified doctor.
