Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
- Your age. Babies and older adults tend to get sicker quicker.
- Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
- Medicines you take. Certain medicines, such as blood thinners (anticoagulants), medicines that suppress the immune system like steroids or chemotherapy, or natural health products can cause symptoms or make them worse.
- Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
- Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.

- Moderate pain (5 to 7): The pain is bad enough to disrupt your normal activities and your sleep, but you can tolerate it for hours or days. Moderate can also mean pain that comes and goes even if it's severe when it's there.
- Mild pain (1 to 4): You notice the pain, but it is not bad enough to disrupt your sleep or activities.
Pain in children under 3 years
It can be hard to tell how much pain a baby or toddler is in.

- Moderate pain (5 to 7): The baby is very fussy, clings to you a lot, and may have trouble sleeping but responds when you try to comfort him or her.
- Mild pain (1 to 4): The baby is a little fussy and clings to you a little but responds when you try to comfort him or her.
Symptoms of infection may include:
- Increased pain, swelling, warmth, or redness in or around the area.
- Red streaks leading from the area.
- Pus draining from the area.
- A fever.
Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in adults are:
- Diseases such as diabetes, cancer, heart disease, and HIV/AIDS.
- Long-term alcohol and drug problems.
- Steroid medicines, which may be used to treat a variety of conditions.
- Chemotherapy and radiation therapy for cancer.
- Other medicines used to treat autoimmune disease.
- Medicines taken after organ transplant.
- Not having a spleen.
Symptoms of a severe allergic reaction (anaphylaxis) may include:
- The sudden appearance of raised, red areas (hives) all over the body.
- Rapid swelling of the throat, mouth, or tongue.
- Trouble breathing.
- Passing out (losing consciousness). Or you may feel very light-headed or suddenly feel weak, confused, or restless.
- Severe belly pain, nausea, vomiting, or diarrhea.
A severe reaction can be life-threatening. If you have had a bad allergic reaction to a substance before and are exposed to it again, treat any symptoms as an emergency. Even if the symptoms are mild at first, they may quickly become very severe.
Usually found in dirt and soil, tetanus bacteria typically enter the body through a wound. Wounds may include a bite, a cut, a puncture, a burn, a scrape, insect bites, or any injury that may cause broken skin. Tetanus can also happen with other infections, like dental infections. It can happen during a surgery or pregnancy and delivery.
A wound can be so small, you may not notice you have one. Or a skin blister could break and become an open wound. If there is any delay in finding or cleaning a wound, there is an increased risk for skin infection and a chance for tetanus to get in the wound. A tetanus infection can start 3 to 21 days after the bacteria enter the wound. Be especially careful about wounds on your fingers and toes.
Many people may not know when they got their last tetanus shot. So it's a good idea to call your doctor to see if you need one.
Make sure to stay up to date on your tetanus shots. A tetanus shot is recommended:
- For a dirty wound that has things like dirt, saliva, or feces in it, if you haven't had a tetanus shot in the past 5 years.
- For a clean wound, if you haven't had a tetanus shot in the past 10 years.
