Cobblers in my country are men who work on your shoes. However, I seem to recall that the term "cob" or "cobbler" can mean Spider elsewhere..
So, hoping your shoes are okay, …here's what to do about a spider:.
Identify and preferably capture the culprit -- many spiders have different toxins. .
Once identified, call poison control and they'll tell you what to do. .
If you don't have a poison control organization, we have a decision to make. The vat majority of spiders are either harmless, or almost so. For them, keep the wound clean, ice-pack it, and -- if you have anything like an allergic reaction (trouble breathing, hives, etc.) call for emergency help. For the others, it's very important to know what you're treating. If you identify a really dangerou spider (Brown Recluse, Black Widow or their brothers and sisters), a trip to the dock may be called for. .
If you opt not to go to the doc, watch the bite. It should get smaller and less painful after one day. If it gets larger, consider running for medical care. At a diameter of 3", definiately go to a doctor. .
Some bites form blisters. These aren't a worry as such. Don't pop them. When they pop on their own, keep them clean and dry and bandaged. .
If you see signs of ulcers forming, or flesh flaking off the wound, or turning dark -- it's off to the doctors you go .
Spider treatment varies a lot because spiders vary a lot from place to place. As I don't know where you are, I can't say how lethal or safe spiders usually are in your region..
Please remember I'm not a doctor. I'm a well-meaning fellow who is likely from far away, and doesn't know your territory. Anything I can tell you is nowhere nearly as good as the information you'd get from a local doctor. (MORE)
