There are three lobes of lungs on the right and only two on the left.

The third lobe on the right is all the way at the top. This is so important because it is completely surrounded by bone which makes it much harder to inflate when you inhale.

Here’s the chain of reaction that occurs when that small lobe on the right does not inflate…

  1. The clavicle (collarbone) and first rib stick together via the subclavius muscle: If there is little to no expansion here, that tiny little muscle stays in a shortened position.

  2. The right neck starts to pull on those upper ribs in an attempt to create more space: Ever notice neck tension specifically on the right side. I’ll be you this is what’s happening. Your body is intuitively trying to even out that airflow expansion.

  3. The right neck begins to pull on the bones of your skull: Ever have a headache just on the right side? These anterior neck muscles also attach to the mastoid process (a part of your skull right behind your ear). This new tension in your neck muscles are now taking your dysfunction and moving it north.

This is one of the many reasons why it is not uncommon to see pain exist on only one side of the body. In particular the right side.

We often get clients that say something like, “I don’t know why but all my issues are on the right.”

There are so many unexplainable pain symptoms that can actually be easily explained by understanding anatomy at this level.

I’m not quite sure why, but these anatomical asymmetries are largely unknown or maybe just largely ignored.
