This response has more to do with the title of your thread than with the initial post you made in your thread.

The muscles in my thoracic region will contract on their own and STAY that way with the pulling tightness that just won't let go. It is constant and unrelenting. When this happens, it means a trip to my pain mgt. doc as it will last for weeks unless medical attention is sought.

Now, to your actual post which is different than what I expected from the thread title. Are you purposefully contracting the muscle and if so, why so "hard" as you describe? What are you attempting to accomplish with this action? That made me think of the trick I was taught as a young child where you press your arm (at the wrist area) hard against a wall for a few minutes and then step away from the wall. Your arm will lift into the air all on its own like some magical trick.

I just don't understand your post. I don't understand why you are contracting your muscles hard and then are surprised they twitch afterward. (until the twitching comes down to baseline twitching).

If you are experiencing baseline twitching constantly, that I have read in several of your posts, why are you purposefully taking actions that will cause the twitching to intensify? I am sorry, I guess I have missed the boat and just don't understand your post.

Please forgive me lack of understanding.
