A WORCESTER Warriors fan hopes brain surgery will ease his agonising cluster headaches, describing them as 'the worst pain known to man'.

Tim Mavers-Chance suffers from a rare neurological disability called Cluster Headaches, sometimes dubbed "Suicide Headaches" because of the intense agony they cause.

The 34-year-old, who has supported the Warriors for the last two years, said the pain is 'commonly agreed by medical professionals as the worst pain known to mankind', including childbirth.

The lifelong rugby fan would love to one day go to a Warriors match at Sixways Stadium but says he has not been well enough, his condition leaving him largely housebound.

Mr Mavers-Chance of Chipping Norton, who follows the club on television and through social media, said: "The condition is notoriously hard to treat and causes attacks of unimaginable pain multiple times a day with very little warning."

The father-of-three was diagnosed with the condition by a neurologist in High Wycombe in May, 2014 following an MRI scan.

He can suffer around six attacks a day and has had to leave his job as a plumber because of the debilitating condition.

Mr Mavers-Chance said: "Since being diagnosed with Cluster Headaches, my life has changed dramatically.

"I live hour to hour, constantly in fear of the next attack. I carry oxygen tanks with me wherever I go and have been in and out of a wheelchair due to the aggressive medication I need to take.

He has even compiled a YouTube video to show what happens during an attack which has already attracted 36,000 views.

Mr Mavers-Chance has since been offered what he calls avant-garde brain surgery which he hopes will help control the horrific attacks.

He is under the care of the medical team at John Radcliffe Hospital in Oxford and has yet to be given a date for the procedure.

He said: "The surgery is designed to put to electrodes in my brain which will send constant pulses across the affected nerve.

"It works in a similar way to a tens machine which is used when women labour in childbirth.

"The surgery will be paid for by the NHS, however, I will require additional care throughout my recovery which my family cannot afford."

Because of the condition Mr Mavers-Chance cannot drink alcohol and has been left house-bound, fearing to go outside in case he suffers an attack.

He said: "The pain is absolutely indescribable. If I had a bad attack and the room was burning down I wouldn't notice."

He has to take medical oxygen which slows down his heart and ease the pain and Sumatriptan to kill the pain.

The operation will involve inserting a stimulator into his brain as part of a procedure called Occipital Nerve Stimulation (ONS).

Cluster headaches (CH) are part of a group of 'primary' headaches named Trigeminal Autonomici Cephalgias (TACs).

Primary headaches are defined as those where the headache is the condition itself, as opposed to 'secondary' headaches, which are caused by external factors, such as accidents or infection.

Mr Mavers-Chance has set up a charity page, www.gofundme.com/clusterhead to allow people to donate if they are able.
