Giving an update so this thread has a possible close. I know so many don't usually give closure.
There for a minute I was really worried and even thought my left chest was becoming sensitive, even when not touching it. It was really hard to get my mind off it but if I did I would forget. Then it pop in my head. It was almost as if my mind causing the condition.
Then this past week, I had to get out and work on my vehicle. It distracted my mind. All my chest weirdness went away except when I move certain ways still, so I know that is for sure there. It's like it's more skeletal and in my sternum, possibly caused a little swelling. I believe it is tied to where I injured and tore my left chest muscle 2 to 3 months ago. I've read about a couple conditions online that can be caused by tore muscles. They can re-occur for months or even years after.
So to sum up, I believe for the most part all my chest weirdness was from an injury. Then my mind ran with it and began to worry. So for the time being everything seems to be ok, minus injury stuff. Almost scared to admit that like it will jinx me. I had 3 women in the last 24 hours tell me that I had beautiful, or gorgeous hair, or that they would like to play with it. It freaks me out when they say that now because I don't want it to jinx me or something. Used to like to get compliments. I still do but my mind is clearly messed up. I can't even take a compliment correctly.
