Me and my sister fell asleep with a spider in the corner of the room last night when we woke up it had gone and be have both been bit, could this be serious?

Wait....one spider in the corner of your room waited until you went to sleep and then decided to bite both of you? Spiders, believe it or not, do not work like this.

How do you know you were bitten by the spider?

What do the wounds look like? Two people getting bitten sounds more like insects than arachnids.

It was waiting for a chance to get even for you stepping on its great, great, great, great, great, great, great, great, great, great, great, great grandpappy.

I agree with the others...more than likely it was something else that bit you both.

I live in the northeast US, where there are NO poisonous spiders. That's not to say a spider bite isn't usually a huge bite. Some swell up several inches across. I had one once that left a volcano with a hole in it, and an infection moved it the hole.

So is yours dangerous? Probably not. Where do you live? And I agree with others, just because you saw a spider doesn't mean that's what bit you - especially both of you.

What happened to your throat lumps? And worries about pregnancy? I'm worried that you are too worried about spiders when something else is what is really on your mind.

Actually Joy, your first sentence is not entirely correct. Forgive me because I am a spider nerd and I just wanted to correct this....nothing personal...it is just something that many people really don't know about (or care to know about! lol)

1) Spiders are venomous, not poisonous. Poison is something you ingest, venom is something that is injected.

2) ALL spiders are venomous. I have had many people argue with me over this but there isn't a spider alive that isn't venomous. This is how they survive. The question becomes, how medically significant is the venom? Most spiders will give you no more than what looks like a mosquito bite as their toxicity to humans is very low. Some can potentially kill you.

3) Where you are, you do have one medically significant species running around, though not very common. The Northern Widow (or Northern Black Widow) is related to a Black Widow and it is in your area, mine too as it turns out. Something I wasn't fully aware of until earlier this year, then I did some research. Their bite, much like the Black Widow that everyone fears so much, can pose a real threat. However, what I have learned about Widows is that generally, they are way over-rated when it comes to how deadly they are. It seems that most people believe a Widow bite will kill you which isn't necessarily true. Numerous Widow bites can kill you, a single one, not so much. Sickly people, elderly people, infants...they could die from a single bite but someone that is healthy will usually need a few at once to cause a real problem.

An interesting piece: It is believed by many that most deadly spiders will bite with a dry bite (not injecting venom) on the first attempt...I guess as a warning. I have read that there are scientists trying to prove this theory one way or the other. I know people that have been bitten by angry tarantulas but had no more than puncture wounds so I find the whole idea interesting. Perhaps the spiders wish to not use their venom unless they really need it.

Thanks for letting me nerd-out and like I said Joy, nothing personal, I just wanted to get that out there. I can't help myself.

And to finish up....to the OP....spiders do not stalk you or seek revenge. If you saw it in the corner of your room, chances are that it didn't see you (they have terrible eye sight). It wouldn't have come to you looking to bite you as it gets nothing from that. The spider will not bite just to bite. The bite serves only 2 purposes: 1) defense and 2) eating.

Glad to learn something, thanks.
I only kill one in several hundred spiders in my house, and rarely take down webs outside.
On the other side of the coin, I sometimes rush out to free butterflies from the webs.

Since I had this first bite I'm covered in them now, and they're huge, and joypulv; I had a fake positive, bloodtest was negative, and the lumps are still there I just don't want to go the doctors.

And I live in england

If two people woke up with bug bites, I would suspect bed bugs.

I doubt I have bed bugs...

Do they look like this?

How do I post a picture?

It look like a small bite and then huge red marks around them

Well, if they have multiplied during the day, I think we can rule out spider bites. This sounds more like something you should go to see a doctor about.

Any suggestions and what they could be?

You went to bed fine and woke up with bites. Sounds like bed bugs.

You are In the UK. Go to a doctor, you have socialized medical, Melissa. No one line is going to be able to help you with a definitive answer.

That was my first thought. You've got free medical care for whatever ails you. Use it. I would put money on bed bugs or another infestation. It would be really rare for two people to be allergic to the same thing as well as it suddenly showing up like that. Stop wasting time online and book an appointment.

Joypulv: Having lived in NJ for the first 25 years of my life, I too can testify that there are lots of Black Widow Spiders. We used to catch flies and dangle them in front of their lair so they would come out and we could see the hourglass.
