Here are the latest tips on how to treat the most common and serious medical conditions so you'll know exactly what to do if one strikes, reports News.com.au.
Burn
"The number-one solution for a burn is 20 minutes under cool running water," Peter LeCornu, national training manager at St John Ambulance Australia, says. "After that, cover it with a loose, non-stick dressing.
"If the burn is bigger than a 20-cent piece, see your doctor or a pharmacist. If it's bigger than the palm of your hand, head straight to hospital." Do not use ice or apply lotions, ointment or fat to the burn. If the burn is deep, seek urgent medical advice.
"If you've just received a cancer diagnosis, acknowledge that feeling a range of different emotions is normal," Nicole Cook, clinical psychologist at Sydney's MindFrame Psychology, says.
"It can be quite overwhelming to think of all the 'what ifs', so try to stay in the moment. Discuss the diagnosis with whoever you feel most comfortable talking to.
"That could be friends and family or a counsellor. If someone close to you has received a cancer diagnosis, listen. It might not feel like much but it's the best thing you can do."
Panic attack
"Panic attacks can be overwhelming and scary," Cook says. "The first thing is to remind yourself you're not in danger and encourage calm thoughts.
"A panic attack will cause rapid, shallow breathing, so try to counter that with slow belly breathing. If panic attacks are happening often enough to significantly impact your life or cause debilitating fear, see a psychologist."
"Give the person five sharp blows to the middle of their back using the heel of your hand.
Failing that, give them five chest thrusts - stand next to them with the heel of one hand on the lower half of their sternum and one in the middle of their back and thrust," LeCornu says. If a child is choking, use back blows. Don't tip them upside down or put your fingers in their mouth or throat.
Sunburn
"Prevention is always the best cure," associate professor Chris Baker, president of the Australasian College of Dermatologists, says.
"But if you get caught out and are suffering from mild sunburn, use a simple moisturiser, such as sorbolene, and a cold compress on the area. Simple is best when it comes to after-sun lotions, and I'd avoid anything that's highly perfumed or has an anaesthetic agent in it."
Heartburn
"Mild heartburn can often settle with a glass of milk and rest," GP Dr Elizabeth Sturgiss says. "For anything more severe, use over-the-counter tablets or liquids." If that fails, seek urgent medical advice to rule out a more serious issue.
Fever

"A fever is considered temperatures above 38˚C," Sturgiss explains. "If you have a fever for more than 48 hours or if paracetamol isn't helping to bring it down, make an appointment to see your doctor.
"If, however, you have a fever as well as neck stiffness, difficulty with bright lights, a bruise-like rash, drowsiness or confusion, get to the hospital. Exercising to 'sweat out a fever' is a myth so don't try it. Children with fevers should be seen by a doctor as soon as possible."
Allergic reaction
"The most common form of allergic reaction is hayfever, which can cause sneezing, itchy eyes and nose, and a runny or blocked nose," Sturgiss says.
"If you're having these symptoms for the first time, see your doctor to confirm the diagnosis. Then, over-the-counter medicines and steroid nasal sprays will help relieve symptoms.
"An acute allergic reaction can be caused by a range of things and cause a number of different symptoms, from itchy rashes and sneezing right through to life-threatening airway swelling and breathing difficulties.
"If it's a severe allergic reaction, call an ambulance and give the person first aid while you wait for it to arrive."
Diarrhoea
"Keep well hydrated by drinking a combination of water and electrolyte solutions frequently," Sturgiss says.
"It's also important to rest. If you've had ongoing diarrhoea for 48 hours, it's worthwhile visiting your GP. If you're vomiting too, don't leave it any longer than 12 hours before seeing a doctor."
Tick bite
"It's crucial you get the whole tick out, so only try to remove it if you've got tick-removal forceps," LeCornu advises.
"With normal tweezers, it's really easy to get the body out but you often leave the head behind. If you don't have the right forceps, get to a doctor."
Sprain

"The message is simple: R-I-C-E," LeCornu says. "That is, rest, ice, compression and elevation. Sit down with an icepack on the area for 15 minutes every two hours for the first 24 hours.
"Also use a compression bandage on the area for at least 48 hours and elevate it for as long as you can."
Migraine
"Make sure it's a migraine and not a bad headache, which can be treated with paracetamol or ibuprofen," Sturgiss says.
"Migraines tend to be on one side of the head and they throb. The best thing for migraines is aspirin washed down with coffee.
"We think spasms in the brain vessels cause migraines, and the aspirin and coffee work together to dilate them and relieve the pain."
Fainting
"If someone blacks out with no warning, they should see a doctor immediately," Sturgiss says. "But if someone feels they're about to faint and then does, it's less serious. Put them flat on their back on the floor with their feet up at a right angle.
"If they don't wake in a few minutes, call an ambulance. If they do wake, keep them lying flat for 5-10 minutes and then ease them up gently. Have them sip some fluids. If they're acting oddly or feeling unwell, call an ambulance."
"The first step is to put gloves on to reduce the risk of infection," LeCornu says. "If the area is bleeding, stop it by applying pressure. Then use water or saline and sterile gauze to clean the area and get any nasties out.
"After that, apply a soft, dry dressing. If the wound can't be cleaned or if there's something stuck in there, that's when you should head to the doctor."
Concussion
"Concussion is the result of a head injury so it always needs to be treated seriously," LeCornu says. "I'd call an ambulance straight away and then keep the person lying down until the ambulance arrives."
Constipation
"Increasing your fibre intake with more vegetables, whole fruit with the skin on and wholegrains, as well as upping water intake, should be the first step," Sturgiss says. "Exercise also gets the bowels moving." If that fails, see your doctor.
Urinary tract infection
"Book in to see your doctor," Sturgiss says. "While you're waiting, keep your fluids up so your urine is almost clear - that will help flush the bugs through. You can also get effervescent drink sachets that will make your urine less acidic so it's less painful."
Depressive episode
"People who are depressed tend to think negatively and be self-critical so an easy tip is to ask yourself whether you'd talk to a friend in the same situation as you're talking to yourself," Cook says.
"Writing your thoughts down and trying to challenge them can also help. So can exercise because it improves mood and sleep quality. Last of all, ask for help - it's never too soon."
Chest pain

"Chest pain that lasts for a few seconds is something that should be followed up with your doctor," Sturgiss says.
"But if chest pain lasts more than a few minutes or comes with difficulty breathing, racing heart or feeling unwell, call an ambulance quickly."
Stomach ache
We've all had that queasy feeling but Sturgiss says, "Severe or persistent tummy pains should be discussed with your doctor, who will do a comprehensive assessment of your medical history and a physical examination.
"There's no common remedy for a stomach ache and they can be caused by so many different things so it's really important to get to the bottom of the cause."
Toothache
"Even a mild toothache warrants a visit to your dentist," Dr Gary Smith, president of the Australian Dental Association Queensland, says.
"The most likely cause of a toothache is sensitivity, decay or a cavity, all of which need treatment. Other causes include fractures, gum disease and even things unrelated to the teeth such as sinus infections and heart disease. Have regular check-ups."

"If a person is having an acute asthma attack, they will have difficulty breathing, trouble speaking and may even collapse," Sturgiss says.
"Help them use their puffers and call an ambulance. If someone has undiagnosed asthma and is experiencing wheezing, coughing or breathlessness when exercising, they should book in to see their GP. It's also especially important for people with asthma to avoid cigarette smoke."
