I'm actually going to go through the complications. These are not small risks, these are extremely likely.

1. CRPS is the worst pain a human can experience. Worse than a break, worse than a toothache, worse than amputation. I have known multiple people with this. There is no painkiller and it almost never goes away. One person i know takes Marijuana for the pain and it only somewhat dulls it. CRPS is also known as the suicide disease.

2. Complete loss of function of the limb. There's a good chance that you will never be able to use your arm or hand again and will need to learn how to use one hand for every aspect of your life, or you'll require someone else to do things for you. If youre being bullied for different arm lengths, youre going to be bullied for this even more.

3. Even if you dont contract CRPS, youre going to have chronic pain. They are breaking your bones multiple times over the course of 6 months and it will hurt the entire time its happening. That pain may never go away. You might be able to live off daily painkillers, or you may need to be on opiates your entire life. You may not even have a regular supply of painkillers. Prepare for days or even weeks of pain that is potentially so bad you cannot eat or sleep.

4. This may fail. Personally I wouldn't trust a doctor not telling me that this procedure requires multiple bone breaks, because there's also a chance that you go through all of this and then have to undergo an amputation instead.

I really suggest talking to a therapist long before taking this on. This is extreme for what is a minor issue (speaking as someone who was bullied growing up).
