What can I do about dark rough knees?

What can I do about my knees and flat feet?

• I have been born with flat feet. It runs in my family. So i'm pretty much cursed with it along with my future kids. I have hurt my left knee twice and never went to a doctor(It's healed now) and I have had arch supports for my flat feet to help my knees. I really really want to start running and getting in boxing but I need to not hurt my right knee which I favored while my left knee was hurt both times. My right knee isn't hurt but it makes a grinding noise when I sit down. I really DO NOT want to hurt my right knee. I plan on getting into boxing and then doing mma but that has a lot of Jiu Jitzu and wrestling and I hurt my knee once while wrestling .Please answer these questions: What does the grinding sound mean and what can I do about it? Will a proper knee brace protect both my knees from popping out or becoming injured while doing a sport? Can I trust a knee brace to prevent my knee from popping out while wrestling? I need the best answers possible. Thank you.

  Woe, you may need some knee bands to control the minimum of your knees bond. But in your case vitamins would be a great source of healing, either it be your bone marrow or structure make sure you are eating well according to your need. Okay one suggestion i would recommend is lay off of the soda any kind due to weak knees and may not compliment your abilities. Here is some information you may want to look at i hope it will help your abilities feel better in the future.
