[|Human|] Hi, I have been getting what I thought at first was something biting me cause it itches and swells up like a bite. In a day it it going away. But I notice it is happening every week or two I get one. I have noticed nothing in my house like a spider or anything that would bite me to cause this. What could it be?
[|AI|]  HiT hank you for asking Chat Doctor. I have gone through your query. For normal spiders only symptomatic treatment will be enough. You can wash the area with soap and water and apply ice pack of pain relief. Over the counter analgesics can be used in case of more pain. Tetanus toxic should be taken for prophylaxis. You should also check your BP and pulse rate. In case of any discomfort approach ER.  Clotting time and bleeding time should be measured. Spiders like black widow can cause adverse reactions.  In such case there will change vital signs and antivenom should be administered. Hope this may help you. Let me know if anything is not clear. Thanks.
