I’ve often heard many amputees (not all) have to learn how to deal with Phantom Pain (feeling the sensation of pain where your now missing limb used to connect to your body).
I believe that description is correct.
Terrible that’s why it’s important to not just take into account the death toll, when it comes to war - but to understand how severe the nature of wounds can be.
The most awful site of all is if a veteran amputee homeless on the streets, sometimes in a wheelchair sometimes not. :( They don’t get much extra lifelong help or compensation.
