I’m 21 and the past 4 years I’ve I strange problems with my breathing I get sharp pains in my chest and if I don’t get enough sleep I feel very weak. I also noticed when I go to the gym I burn out really quick and which ever part I work out gets real shaky and is hard to move. My guess is it has something to do with my blood because I also notice my arms and legs fall asleep very easy. I’m also having problems with my digestive track, Food isn’t moving through my stomach.
