Doctor explains how to tell if your headache is a cold - or a sign of a brain tumour

A medical professional has offered advice on how to distinguish between a harmless headache and one that could be a sign of something more serious. Dr Baibing Chen highlighted two specific symptoms as potential red flags, stating: "If a headache suddenly feels different, such as thunderclap headache, or it's lasting longer [than usual] it could be of something serious like a bleed or tumour or aneurysm."

While most headaches are typically nothing to worry about, the so-called 'thunderclap headache' is described by the NHS as causing "blinding pain unlike anything experienced before," akin to being struck in the head, reports the Mirror.

This type of headache is considered a medical emergency, with the health service advising those affected to call 999 or get to A&E immediately. US-based Dr Chen informed his Instagram followers that sudden thunderclap headaches could indicate a burst blood vessel in the brain, potentially leading to lifelong disability, coma, or even death.

He also warned against neck manipulation - a technique used by some chiropractors - which could increase the risk of developing serious conditions. Dr Chen further cautioned: "Forceful neck adjustments can carry a rare but serious risk, and that is vertebral artery dissection... A stroke in the brainstem can lead to one of the scariest things I've ever seen and it's called 'locked-in syndrome', where you're fully aware but can't move or speak."

Headaches might be pushed aside as a common ailment, but doctors are warning that they could signify something far more serious – like a brain tumour. It’s recommended to see a GP if headaches start happening more often or create new patterns, advised Dr Chen who is also advocating for regular sleep as part of maintaining overall well-being and preventing headaches.

"Chronic sleep deprivation can increase the risk of dementia and lead to a host of neurological issues. So even with a busy schedule at the hospital and coming home to two little kids I try my best to get quality sleep and get at least six hours when I can," added the neurologist. This underscores the NHS guidance that adults should aim for seven to nine hours of quality sleep nightly, despite recent findings that Brits are missing nearly 25 days' worth of sleep annually.
