article: This gruesome video shows how a man popped a huge cyst in his arm with a needle, screwdriver and a pair of pliers. The man, known only as Jason, from Vancouver, uploaded the clip to YouTube after his wife filmed the stomach-churning moment. It begins with him explaining exactly how he will pop the grape-sized growth on his wrist. He says: 'We have the pliers, they're going to hold onto the needle which will then be smashed into my cyst with the end of a screwdriver. 'It should be pretty cool.' The man, known only as Jason, uploaded the video to YouTube of his unique way of popping a cyst - using a needle, a pair of pliers and a screwdriver. Pictured is his sister in law putting the needle into the swelling . As Jason's sister in law hammers the needle deeper into the cyst with the handle of a screwdriver, he emits loud cries of pain . First, he lays his left arm down on some kitchen roll on a table so the lump is easily accessible. His sister-in-law then inserts the needle into the cyst and holds it in place with a pair of pliers as he winces. She then begins the horrifying process of hammering the needle deeper into the growth. Sharp cries of pain are heard from Jason with each hit. Astonishingly, though the process seems too agonising to bear, Jason says: 'I think we can go a little deeper'. After one last hammer – which was once again met with a loud moan – he says: 'It's in there pretty good. Now we've got to pull it out. Dr Arun Ghosh, a private GP in Liverpool, condemned Jason's method of popping his cyst with a needle, pliers and a screwdriver. He told MailOnline: 'We advise not draining minor ganglions. 'They just get bigger and bigger. We only drain it if they are very large and hindering the use of the hand. 'It’s wrong to pop a ganglion with a needle and a screwdriver on so many levels. Traditionally, ganglions would be 'bashed with the family bible', but doctors do not advise this . 'From a hygiene point of view you’ve got to sterilise your equipment. We would never insert a needle that would be used in the house. They are covered in millions of bacteria. 'You can never control the force by using a screwdriver, and that’s dangerous. 'There are very fine arteries and nerves in the hand, and they’re so easy to damage. 'If they are damaged you get irreversible pain. If you think how often you use your hand that can be debilitating. 'There used to be a myth that you should bash a ganglion with a family bible to burst it. 'That’s caused problems with the fluid going into the wrist joint, causing carpel tunnel syndrome: swelling inside the wrist. 'If we did treat it, we’d do a needle aspiration, which means sucking out the glue-like pus. 'But that would be what is known as "aseptic", meaning the pus would be drawn out into the syringe and would never touch the wound, to prevent infection. 'We would also do it under ultrasound so as not to damage the fine veins and arteries in the hand. 'If you have a ganglion or a swelling you must go to your GP and they will advise whether its OK or whether it’s best to be left alone. 'Then it will be followed up and receive proper after care.' 'I'm going to see if we can get the fluid squirting out if it does.' Moments later, he takes the needle out and asks the camera to zoom in on his arm. As he squeezes the cyst, sticky, translucent jelly comes rushing out and gathers in a pea-sized ball. 'Let's see what the consistency looks like,' he said as he rubs the gluey substance between two fingers. He adds: 'This is probably the grossest thing I've ever seen – since the last time I've done this. 'This will probably do the trick for three or so months until I have to pop it again.' Uploading the video to YouTube under the name 'The Wrist Cyst', he promises to upload another video in another three months time when he pops the cyst again. Unsurprisingly, medical professionals do not advise using Jason's method to treat lumps found on the body. Dr Arun Ghosh, a private GP in Liverpool, explains that Jason's cyst is a ganglion, a fluid-filled swelling that develops near a joint or a tendon. They are made up of a thick jelly-like fluid called synovial fluid, which surrounds joints and tendons to lubricate them during movement - and occur when this fluid leaks out and collects under the skin. Ganglions can occur alongside any joint in the body, but are most commonly found on the wrist, hand and fingers. Generally harmless, if they do not cause any pain, they can be left alone and will disappear without any treatment. Dr Ghosh said: 'We advise not draining minor ganglions. They just get bigger and bigger. We only drain it if they are very large and hindering the use of the hand. 'A ganglion is a fluid-filled sack. If you start the drainage process, the bigger and bigger the sack will fill. 'This is the issue this gentleman has caused, he’ll need to drain it more often.' Traditionally, ganglions were treated by being 'bashed with the family Bible', but this is no longer recommended, as this could cause the fluid to disperse and cause carpel tunnel syndrome - a swelling in the wrist - he added. Dr Ghosh added Jason's method was also not advisable either. He told MailOnline: 'It’s wrong to pop a ganglion with a needle and a screwdriver on so many levels. It’s unhygienic, you can’t control the force and you could damage the nerves in the hand. 'From a hygiene point of view you’ve got to sterilise your equipment. We would never insert a needle that would be used in the house. They are covered in millions of bacteria. 'You can never control the force by using a screwdriver, and that’s dangerous. 'There are very fine arteries and nerves in the hand, and they’re so easy to damage. If they are damaged you get irreversible pain. If you think how often you use your hand that can be debilitating.' He removes the needle and squeezes the cyst, and a ball of sticky, see-through jelly-like fluid emerges . Jason rubs his fingers together to show the sticky consistency of the fluid that comes out of the growth, which doctors explain is synovial fluid, which surrounds joints and tendons to lubricate them . At the end of the video, Jason says the cyst will need draining again in three months. But doctors strongly advise against his method - and say ganglions do not normally require treatment . If the cyst needs treatment, the fluid should be drained out with a needle and syringe by a doctor, or cut out in a surgical procedure. Dr Ghosh added: 'If we did treat it, we’d do a needle aspiration, which means sucking out the glue-like pus. 'But that would be what is known as "aseptic", meaning the pus would be drawn out into the syringe and would never touch the wound, to prevent infection. 'We would also do it under ultrasound so as not to damage the fine veins and arteries in the hand. 'If you have a ganglion or a swelling you must go to your GP and they will advise whether its OK or whether it’s best to be left alone. 'Then it will be followed up and receive proper after care.'
