I must of misheard the doctor explain the anatomy, but after reviewing the report, it says there’s intramuscular course of the brachial plexus through the anterior scalene muscles.

This means that the some of the nerves of the brachial plexus actually pass through the scalene muscles as opposed to running along the outside of the muscles. I wonder how significant this is with TOS. There’s no doubt to me that with the nerves passing through the scalene muscles that this just makes it easier for the nerves to become compressed since they are not running freely along the outside of the scalene muscles.

Although now I’m worried because it’s been 2 weeks and 3 days and I have absolutely no improvement from botox injections yet. I was hoping I would see something by now and fear that I won’t see any improvement, which makes my case for surgery that much harder. Unfortunately, there’s no doubt my TOS symptoms are real. Just wish the botox would work and make everything easier for me.
