Wow, glad it wasn't worse.
The worst I ever had was I paralyzed my thoracic nerve on my left side.
I had injured my shoulder(tore some cartilage) during a football practice. I jumped back into benching and pressing to heavy to early. My serratus muscles on my left side don't "fire" like they should, and don't pull my scapula down and in. So my humerus rolls foreword.
I constantly have to be aware of my posture, and form while lifting. I could create further injury with too much weight.
