Rib Cage

Help, mommies. Masyado na ata akong stress na kahit anong bagay ikina papraning ko. This started days ago na parang masakit ang dulo ng left rib cage ko. And then kagabi, I tried to feel my ribs, (both ribs) parang mas labas yung left rib cage ko kesa ang right, di ko naman masyado na fefeel pag hinahawakan. Is this something to be worried, mommies? Baka may say kayo dito. Please, I need words po or advices if this is something I should check on doctors. Thank you po.
