Finding a spider in your bedroom or bathroom can be uncomfortable, but most spiders are not dangerous to humans. In fact, many bites people blame on spiders are caused by other insects or skin conditions.
Still, some spider bites can cause significant reactions.
1. Redness around the bite: A mild reaction may cause a small red area, itching or tenderness.
2. Local swelling: The skin may become slightly swollen around the bite site.
3. Increasing pain: Pain that becomes severe or continues worsening should be assessed by a healthcare professional.
4. Blistering or skin damage: Certain spider species can cause more serious local tissue reactions. However, a blister or dark mark alone does not prove that a spider caused it.
5. Muscle cramps or sweating: Some medically significant spider bites can cause muscle pain, cramps, sweating or other body-wide symptoms.
6. Serious allergic reactions: Difficulty breathing, swelling of the tongue or throat, dizziness or fainting may indicate a severe allergic reaction and require emergency help.
What should you do?
Wash the affected area with soap and water. Apply a cool compress wrapped in cloth and avoid scratching or squeezing the skin.
Seek medical advice if pain is severe, swelling spreads, the wound worsens or you develop fever or other unusual symptoms.
Do not cut the skin, suck the bite or apply chemicals. If you see the spider, photograph it only if you can do so safely.
Most suspected spider bites are not emergencies, but worsening symptoms deserve attention.
