Ear infection, put cloves of garlic in your ears.
Foot fungus, put cloves of garlic in your shoes, socks or between your toes. Garlic has anti-bacterial properties.
Vaginal yeast infection, eeh... maybe try the garlic and see what happens.
Tooth ache and it's saturday night and your dentist doesn't work weekends? Take a paracetamol/ibuprofen pill and place it where it hurts, like if it's in the molars put the pill there and bite down, gently, just to hold it in place. It will slowly dissolve in that area and decrease the pain and the swelling. Remember that one, it might come in handy some day.
Do you have food poisoning and having trouble eating, drinking or keeping anything down? Slice a chilled Conference pear into strips and dip them into filmjölk(it's like kefir/yoghurt but obviously better because I grew up with it), then put them in your mouth at whatever pace you feel comfortable with. The pear is so soft that it slowly melts away, the body will absorb the water and the sugar that it is tricked into ingesting while the filmjölk/kefir/yoghurt contains helpful bacteria that soothes the stomach. After a while the body will start to accept drinking small amounts of water or even eating/keeping down something inoffensive and easily digestible.
Seriously, this works, besides it being my personal go-to cure I've helped several friends feel better and stop projectile vomiting with my homegrown pears and filmjölk remedy. It needs to be the big, ripe and specifically Conference pears though. D'Anjou can go fuck themselves, I'd rather eat a pine cone, those are easier on the teeth and just like anime, nashi was a mistake. Kaiser is too sweet and too soft.
Is there any remedy for sneezing extremely loud?
?
Yes, I can relax and let my sneezes out as a sigh(people find it weird). I have that thing where if I go from the dark into bright light(from winter darkness into a store) I might chain sneeze 5-15 times in under a minute, so there's been a lot of practice. It's more cathartic to have that big dog sneeze but it is not always appropriate, it's loud and people assume someone is sick and spreading disease if they're sneezing a lot, can't blame them for that but it's not a good impression to give.
edit:
Lifehack(s): to practice not sneezing loudly, twist a piece of toilet paper into a sort of soft, pointy pipe cleaner and stick it up your nose, you will know when you find the spot, spin it a bit and now you have caused a sneeze. Repeat until bored or until the person on the other side of the phone accepts that you have a cold. Wild coughing can be caused in the same way with q-tip in the ear, that doesn't work for everyone though.
Eat toothpaste if you want a one hour fever, the body really doesn't like fluoride.
I made the big switch to drinking mostly water last year and it really does help. I never understood how people could drink it because as a kid I always thought it was gross. What I didn't realize was that I just didn't like cold water, I like it room temp with no ice. And once I figured that out I drink it every day.
Other than the daily cup of tea or coffee I pretty much only drink water - it leads to people at restaurants thinking I'm cheap, lunch restaurants where a soda is included say "oh, but there's a soda included". Don't want it.
It makes drinking the rare juice, milk or can of soda a special occasion to be savored, so many flavors and whole milk is an experience if only consumed a couple of times per year. Drink too much or too often of something and the flavors dim. Ask someone that drinks 4+ cans a coke per day what the actual taste of coke is and they will be lost, they don't notice it anymore. So if you like soda, drink mainly water, it will make the soda better.
