Hi, River! Nice to meet you here. I know what you mean, looking for more information to try to get an idea of what's going on. Let me see if I can give you a little info to help you out here.

SID is the original acronym for what is now mostly called SPD, or sensory processing disorder. Most of the places you'll see will call it SPD now.

The information that you talk about does sound a lot like tactile sensitivity. Different people have different levels at which things are over- or under-sensitive in the SPD world. Often, people will have sensitivities in several different senses. Are you also sensitive to bright light? Do certain sounds really drive you crazy? Are you overly sensitive to perfumes, cleaners, etc? Or is it opposite, where you really seek bright light, ride the scariest rollercoasters, play your iPod at the highest sounds, dream about bungie jumping? These would be corroborative signs. One place where you can take a survey of likely signs is at this site.

Another thing to consider is that many people who are diagnosed ADHD have sensory issues that cause the concentration difficulties. More and more people are finding out that working with their sensory issues can help their ADHD tremendously.

I hope this helps. If you have any more specific questions or concerns, please feel free to ask. Also, we'd love to get to know you and know more about you. We like for this board to be our SPD home.

Good luck finding the information you need!
