Okay deep breaths. The first thing you need to do is not panic. I know it’s terrifying but you can do this. If you can, get a washcloth or a paper towel and wet it with cold water. Hold it over the cut for a while and apply pressure. You’re gonna need to look for either a large bandage or some gauze. If you have gauze, cut a square so it will cover the cut comfortably, then apply some antibiotics and tape the gauze on or wrap an ace bandage around it to hold it in place. You could also cut the toes off of a sock and pull it over to hold it on as well, or wear tight pants if it’s on your leg. After that you’re gonna drink water and try to sleep. You can do this.

go to the hospital please if it’s numb and won’t stop bleeding if it was just one then you can lie your way out of getting sent to the hospital but you don’t want to bleed out or lose your arm

If you're seeing fat, its recommended to go to a medical professional to get it stitched. If thats not the case, try to close it up with (makeshift) steristrips and a bandage. You can make your own steristrips by cutting medical tape or a bandaid in strips. Pull the edges of the wound together and put a steristrip on, repeat untill its closed up. Dont take the steristrips off for at least 10 days, if you do the wound might open up again. Usually they fall off themselves.

Was it spraying and was the blood pulsating with your heart? If so, you hit an arteriol or an artery, which definitely needs medical attention

feel free to send me a pic, if you want, and i can let you know how to treat it? you might need to go to hospital, but might be able to avoid that depending on how it looks.

That is an IMMEDIATE trip to the hospital please please please go if you went to sleep, woke up, and it’s STILL bleeding even a little that’s like bleeding out level bad plus you may need to get it disinfected with the sock. Please for your own safety go to the hospital 

Please go to the doctor

Okay, first off is the blood pulseing like spewing with a rhythm. If yes you really need to go to the doctor, you hit an artery. If not clean up as best you can, use some neo sporin if you have, and then if you can make it to the store get steri strips and bandages. If not make your own as seen here some sort of compression fitting will help stop it bleeding. maybe cut the end off a sock and pull it up your limb or leggings or an ace bandage.

Has the bleeding stopped? Could you describe the cut, or what you saw inside of it?

It’s always best to get medical care if possible, but if not, just focus on taking care of yourself as best you can. Clean the area gently with some warm water, pat dry, and close with steri strips or medical tape if it’s gaping. I know it’s scary but try to take a deep breath, you’ll be okay.

I hope the bleeding has stopped and you are OK. I know it's easy to say, but try not to panic if you find d yourself in the same situation again, keep calm, put some sort of clean cloth or bandage over it, apply pressure (I know its hard when it hurts, but it's important to do) and if its on your arm, lift your arm up and hold it there to try and slow the blood flow. I hope you have someone you can trust and talk to, and don't beat yourself up for self harming, you really aren't alone.

Ik this isn’t related to the post but it’s refreshing to see people actually helping and giving advice, keep it up y’all. And OP, be safe

Good to hear that! I was worried.

Are you okay OP?

I have gauze pad , gause bandages, fabric bandages, plastic surgical tape , paper surgical tape I couldn't find steri strips

how deep are you talking? here are some things to do:

1. pressure to stop the bleeding. if you have gauze, USE IT. if you don't, a clean rag or (not nearly as recommended) paper towels work in a pinch. don't use toilet paper or tissues, they tear too easy when wet. hold it onto the wound firmly and don't peek at it. once you're SURE the bleeding has stopped, you can remove but be so careful.
2. do you have any saline solution? i would really recommend washing it out with that. don't use things like nasal spray or contact solution even if it says saline. pure saline solution only. you can also make your own! 1/2 tsp salt for 1 cup of distilled water. you can make distilled water. i know you're in a pinch right now, so boiling some water instead could be fine.
3. keep it covered. deep wounds are very prone to infection. wrap it up.

you should go to the hospital if it is ANY one of the following things: appears to be gaping, won't stop bleeding, is down to the fat layer, won't appear closed when you try to push it together, nicked/severed any veins or especially arteries, etc. generally, if you cut deep, you'll want to go to the hospital asap.

To stop bleeding, put pressure on wound for 15 minutes, if it does not stop bleeding go to the hospital. If the blood is pulsing, it's either an artery or an arteriole, if it's an artery you can bleed out in five minutes without pressure and you urgently need medical help if you do.

If it's a vein or an arteriole, even if the bleeding stops they tear open easily and you will be losing more blood than you should be, so unless you're literally unable it's very recommended to go to the hospital.

If you hit hypodermis/beans, it is highly recommended to get stitches within an 8 hour window after making the cut. Anything below beans is 100% time to seek medical help, it's untreatable at home without severe risk of infection and generally at that depth you're very at risk of hitting important structures like blood vessels, nerves, muscle, tendons...

As for treatment of beans past heavily recommended visit to the hospital for stitches - within 8 hour window if you can't get stiches use steri strips or butterfly bandages, put topical cream on bandage and bandage the cut all the while keeping an eye out for infection. Steri strips and butterfly bandages are also good for dermis-level gaping wounds.

I am by no means a doctor so take this with a grain of salt, but I know you should take a clean towel and apply pressure to stop the bleeding, you should really use a towel, but if you're going to use a paper product don't use toilet paper. If the cut has reached subcutaneous tissue, (aka hypodermis or "beans") or deeper that does require stitches. I have heard of people hitting hypodermis and going to the er and they just apply a butterfly bandage, but it's better safe than sorry. I don't have the best advice for aftercare because I've never gone too deep but I've heard you should clean the outside of the wound with unscented soap and water, and then apply an antibiotic ointment of some kind (like neosporan), and if you want I use antisceptic sometimes. As for bandaging I don't think I have any good advice or tips because I don't really know but I do know butterfly bandages are good for anything gaping and you can make a makeshift one with two bandaids. Good Luck! You can find some really good aftercare tips on here and also tumblr which I really recommend because they probably describe it a lot better than me. Again I'm by no means a doctor, these are all just thing's I have heard and picked up on, stay safe!

I just had a look. Keep it covered, change the bandaid every few days or when it starts to come off and make sure to clean the wound when you do. If you have some antiseptic cream then you can dab a little onto the inside of the bandaid.

If you can find something to close it with then that would be ideal but it will heal ok if you don't, it will just take a long time (a month+) and will leave a big scar. I used to use small strips of medical tape to close mine and then stick a bandaid on top.

How deep is it?

I think he meant mm..

Generally if a cut doesnt begin to close/stop bleeding within the hour, stiches should be saught out. Please go to the hospital.

Sounds like you've cut to or through the subcutaneous tissue and yes you need stitches. Don't fucking do it yourself. There's a roughly 100% chance it will get infected which can lead to tissue necrosis, amputation, sepsis, and death. Go to the ER.

Pretty sure that's going to need stitches. You should see a doctor. I don't know the laws in England, but I'm pretty sure they can't admit you into psychiatric care unless they think you might kill yourself or hurt somebody else. Generally though, if you're going to the hospital for care that suggests you aren't planning to hurt yourself. Plus, they would need your parents to sign off on it since you're a minor.

do realize kids have left themselves in permanent pain cutting, or lost use of fingers> i was a teacher and saw one girl hit a nerve that was close to her skin and left part of her hand paralyzed, another hit a nerve and was left with permanent pain in her arm that no medicines touched.

See a therapist. You dno't go to a psych ward unless suicidal

Go to an emergency room. They have seen it before and won't believe any bullshit story you concoct about working on your wood carving skills and the knife slipped. If you nicked a tendon you can be crippled for life.

Go to A&E. They won't send you to the 'loony bin' as you put it, or tell anyone anything you don't want them to as long as they aren't concerned that you aren't a further risk to yourself.

They will likely signpost you to further help and support, which it sounds like you need.

For heaven's sake get it seen to medically. These kinds of cuts get infected and like another poster said it can lead to sepsis, necrosis, all sorts of nasties. And even if not it, without proper stitches it may not heal particularly well otherwise.

If you need medical attention you need medical attention. I know it might be hard but you need to tell your parents what happened or it could get infected or something. Please tell your parents and get medical help

It’s against the rules in here to offer medical advice, so you may have to find that yourself. If it’s showing signs of infection or still bleeding please get medical help. Depending on your location you may be granted confidentiality by law, if you are then they can’t tell your parents.
