So you'll see... the pain is nothing enjoyable but in the end pain is not our enemy. Actually it is our friend telling us: "hey... something is not right here... something is out of balance... have a look at it and correct it...".
Literally this is what the pain does. If we were more conscious and aware of it then we would be able to prevent a lot of problems before they also get serious. And I am not talking here only about the health problems. Together with it there goes a series of consequences and other difficulties on many levels.
Just look at the case of this girl with the knee pain. Now she cannot walk and she needs of other people to buy her food, sometimes cook for her, take her around and help her with her responsibilities. There is a whole chain/pyramid of problems which affect many people around and the whole world.
This is just another example of how every single person - although we think of us as "small and insignificant" - is constantly changing/creating/shaping this whole world in which we are in. Just think of it how it would be in this world if everybody was aware and did not ignore the little pains in our bodies and instead corrected them before they get worse. This would make a huge impact on the quality of the whole life and not only humans but also animals, nature and everything. I am not exaggerating with it. This is all common sense and logic.
So I recommend that you do not ignore pain. Don't fight it with pain killers and rather become friend with it and listen to its advice when it talks to you. Don't take unnecessary risks for example by saying "I am going to be alright" and you continue doing what you do despite of the pain. Our body has a compensation mechanism and it can cope with it for some time but once you cross certain point there will be consequences to it and I am certain that you will regret it. You don't have to take my words for granted. Find people who live in pain all the time and ask them.
If you become friend with the pain and you listen to it when it talks to you then you will not only improve drastically the quality of your own life but also everybody else on this planet.
