It is very well known that the most sensitive part on your body parts to pain is your balls.[9] And definitely, you know how to protect your balls from physical harm.

Follow @newslexpointApart from your balls, these 5 other parts on your body can also hurt like hell if they get the slightest tap, whack, prick, kick, or bump, too.
1). Your fingertip
The ends of your fingers are more sensitive to pain than almost any other part of the body parts,[4] according to an Annals of Neurology study. [12]That’s why tiny injuries like paper cuts and finger pricks can cause a grown man to wince.
Your fingertips are densely packed with nerve endings, which send pain signals straight to your brain. And more nerve endings equal more pain signals.[5]
And speaking of your brain, the area that feels pain has an especially large amount of space devoted just to your fingers,[1] says William Binegar, M.D., the medical director of Pain Care Boise in Idaho.
So when the nerve endings send up pain signals from your fingertip,[7] the pain is perceived as stronger than pain signals from other parts of your body parts, like your arm.
2). Your shin
Your tibia, the bone in the front of your lower leg has very little muscle or fat covering it,[3] says Dr. Binegar.
That means there’s no padding over the bone to protect you if you’re struck,[11] he explains. Even the slightest bump from a coffee table can cause you to double over in pain and a kick in the shin can leave you down for the count.
3).The arch of your foot
Step on a Lego with the ball or heel of your foot and you’ll grimace. [8]Step on the same piece with the arch of your foot, and it’ll be tough to hold back a scream.
The reason for the difference in sensitivity: [9]Your foot’s ball and heel pound the ground hundreds of times a day.
“These areas take a constant beating and develop thick skin.[13] These callus formations allow the skin to withstand greater stress,” says podiatrist David Blackmer, D.P.M., founder of Blackmer Foot and Ankle.
Your arch, on the other hand,[10] has thinner skin so the nerves underneath are closer to the surface.
4).The front and back of your knee
Like your tibia, the front of your knee doesn’t have much in the way of padding from muscle or fat.
Plus, the top layer of bone in your knee cap, called the periosteal layer,[2] is loaded with sensory nerves, explains Douglas J. Spiel, M.D., a board certified radiologist who specializes in interventional pain.
The back of your knee cap is also unprotected.[4] It sits in a ridge between the middle and the sides of your thigh bone, or femur.
“When it gets banged up, you bruise the back of the knee cap and the femur,” Dr. Spiel says. In other words, you’re getting two hits and pain signals from two places for the price of one.[16]
5). Your funny bone
The funny bone is actually not a bone at all,[7] it’s just a playful name for your ulnar nerve, a huge nerve that runs on the back of your elbow.
This nerve sits next to the bone in your upper arm called the humerus. ( That’s where the “funny” name comes from ).
Since there’s barely any padding to protect the ulnar,[4] the nerves fire off more easily when the area is hit.
“Nerves are composed of different fibers,[3] some of which respond to touch, and some of which respond to pain,” says Dr. Spiel. You guessed it: Your brain interprets a funny bone blow as intense pain.[1]
And because the nerve also sends signals in the other direction, towards your hand, you might feel pain all the way through to your fingers too.[9]
