- Look at my thumbs doc! I thought technology was supposed to improve health, not cause new medical problems! I've already had BlackBerry thumb because of Twitter. I think I'm going to sue RIM and Twitter because now, I'm getting PDA Nail!
Here's a snippet: "We describe two cases of traumatic thumb nail dystrophy associated with using a PDA keyboard for several hours per day... In conclusion, biomechanical stress resulting from overuse of PDAs may result in various types of nail dystrophy. We suggest the general term 'PDA nails' for these nail abnormalities."
So, what do your thumbs look like? Are your nails turning dystrophic? Image Source: Access Emergency Medicine I
