hey so i feel like i cant take a deep enough breath, like i feel like i need to yawn but cant. its gotten worse, i feel deprived of air 24/7. went to clinic they did x rays of neck and chest, came up clear. took their ten minute asthma treatment with no effect. not gaining or losing weight so i dont think its thyroid. thought it was tonsils, got a steroid to help with no effect. any ideas would be appreciated, thanks
