Hello friends, my problem is really interesting, the middle of the chest is the place we call the faith board, the same finger crackles like crunches, there is no pain, etc., but I feel bad psychologically. I think this day started after I did dips on the flat bar again, then I couldn't open my arms and my chest, as if my muscles were too tight then there was a pain but now there is no pain when I reach for something after getting up in the morning or when I hang on the pull-up bar, that is, when I stretch the chest longitudinally, what kind of problem can it be? it's been like this for about 2 3 months
