I am overweight but relatively active... I play paintball every two weeks... And I dont eat that much.. And at night when im about to lie down to go to sleep I start getting a tight chest and then I can't get deep breathes with out a lot of work...But once I achieve this breathe I feel absolutely fine for like 10-15 seconds then im back at it... But when I watch a movie or something its not there... Always at night right before bed.. And tonight is exceptionally different.. It is really hard to get a deep breathe.. Hurts around abdominal area... And im getting dizzy after these breathes...Is this a health problem or is this all in my head??
