Ever turned to Dr Google to work out what that pain is and whether it's going to kill you?
Search engines can sometimes give more questions than answers, but one Australian study has found they can actually help when it comes time to see a doctor.
More than a third of 400 adult patients surveyed at two Melbourne emergency departments - St Vincent's and Austin Health - said they searched their symptoms before coming to hospital.
Contrary to perceptions this could lead people to "flood" emergency departments with less serious health problems, study co-author Dr Anthony Cocco said the practice was generally helpful - as long as patients went to reputable sites.
"Researching allows patients to be able to clarify and sort out what they're feeling," he said.
"Most notably, they were able to ask more informed questions of their doctors and communicate more effectively."
Chest, stomach and back pain as well as headaches were the most common symptoms searched.
Of the 139 people who looked up their symptoms before going to emergency, 86 did so more than 24 hours in advance.
Most people who looked up health issues used the top-ranked sights on Google and did not spurn or doubt their practitioner's advice because of what they found, Dr Cocco said.
"I think that would be very reassuring for doctors."
However, some patients (76 of those surveyed) agreed looking up symptoms made them worried or anxious.
"Obviously, anytime you're unwell you're a bit anxious. People coming into emergency are coming in on their worst day," Dr Cocco added."But certainly our research is not indicating that it's leading more people to come into emergency."
'Immensely valuable'
Erica Stevens lives with Myalgic Encephalomyelitis (ME) - the complex condition commonly referred to as Chronic Fatigue Syndrome.
Ms Stevens said she has seen at least four different medical practitioners since first being diagnosed with a non-specific virus two years ago.
She said each practitioner, while well-meaning, did not know a great deal about her condition, and being able to look at information online and bring it to her sessions has been extremely beneficial.
“ME is a very complex illness. Not all GPs and allied health practitioners are aware of the complexity and the severity,” Ms Stevens told SBS News.
“Finding information online has been immensely valuable.”
Previous studies have found some medical professionals do not like it when patients do their own research.
Ms Stevens said she has experienced otherwise.
“My doctor was quite welcoming of me being proactive. He actually mentioned in a referral that I'm a highly motivated patient who takes an active interest in my health,” she said.
Dr Cocco said doctors need to acknowledge their patients may be doing their own research.
“I think patients and doctors should be openly discussing this, especially knowing that patients will trust a doctor’s information over the internet.” he said.
“But it’s definitely something we should be encouraging. Hopefully it will lead to a better overall experience for everyone involved. Nothing will replace a medical consultation."
