That's good to hear. I'm sure your arm will be fine again.
A couple of years back a granite pillar fell on my foot. It sounds like a little accident but my foot was completely crushed and some of my bones splintered. It was the most painful thing I ever experienced. It took a long while after surgeries to walk properly again but now I can even run.
I had to stay in bed for a couple of months and after that I started walking. Hmmm I'm not actually sure how long it took. It felt like ages but it couldn't have been that long.
