Professional athletes and sportsmen get injured just like anyone else. When this occurs, some injuries require surgical intervention. This can be fatal to their careers but it does not have to be necessarily so. The recovery process after the intervention greatly depends on the mental health of the athlete.
Many of them will battle with dark thoughts how their lives are over, how all the invested time was a big fail and they got nothing done despite all the investment. They will be greatly disappointed with themselves and with life in general. Still, there is one good thing in this. Professional athletes have whole teams of experts available to them that will guide them through the whole process and convince them that it is totally normal to get injured in their line of work and that it happens even to the best.
This sort of thinking can reflect very positively on the mental health of the athlete, giving him the much needed and necessary strength to push forward and move away from the unfortunate event. Still, not every athlete has this privilege and not all of them have the same mental strength that will get them through the worst. Most of the time, they are their own worst enemies and the negative thinking can greatly slow down the recovery process.
This will further reflect negatively on their overall shape and their performance might never be the same. The best thing to do is not think like this at all. You may not have the same resources as the professional athletes but, you can learn from their examples and try to remember the most important thing that you are the one who holds all the cards and everything you do will reflect on you and your sports career.
If you wish hard enough to get better, you will eventually. If you tell yourself that you can make it through it, you will. It is important that you take enough rest for your injury to heal and go to rehab. Also, ask around about active compression and trans-cutaneous electrical nerve stimulation.
