Hi Most of the times I feel I don't have enough breath which makes me yawn more often.In an hour I get the urge to yawn for more than 30 times and the condition prevails the same regardless of the amount of sleep I have.Also am not able to speak continuously as I get the urge to yawn or take a deep breath between my speech. suffering for more than 4 years but was able to identify recently as the condition got worse.what could be the reason? what kind of test should I take? Can this be solved by doing simple breathing exercises? In addition to this I also get mid back pain(around left back ribs) often. Please suggest me a treatment for this.
