Pain is a general term that describes uncomfortable sensations in the body. It stems from activation of the nervous system. Pain can range from annoying to debilitating, and it can feel like a sharp stabbing or a dull ache. Pain can also be described as throbbing, stinging, sore, and pinching. Pain can be consistent, can start and stop frequently, or can appear only under some conditions. People respond to pain differently. Some people have a high tolerance for pain, while others have a low tolerance. For this reason, pain is highly subjective.
We have all heard before that health is wealth, and we know the importance of a nutritious diet. Still, it's easy to grab fast food to save time in our busy lives. It's vital to eat healthy foods because they help in "building muscle, sharpening your mind, or strengthening your heart" (via Eat This, Not That!) We all probably know fruits and vegetables are better for your health because they have more nutrients than a cheeseburger, but many of us tend to go the easy route.
You probably learned, way back in high school, that your period typically happens on a 28-day cycle. While there are exceptions (for instance, it's perfectly normal for your cycle to run between 21-45 days when you're a teenager and 21-35 days once you're an adult — via Verywell Health), the bottom line here is, you should expect to see your period make its appearance approximately once a month.
