Whenever i try to sleep in night, my throat become tight and im unable to swallow salaiva or air, its like something stuck in my throat . I dont feel anything in day or during eating. Only in nights it happens. When i lie down to side also the tightness in throat is more. I feel like suddenly my tongue has become more lengthy and feel like keeping it outside. I feel breathless. It is intermittent issue. And seems to happen mostly in summers to me. I had done many tests but everything is normal. I faced this one year back and it's repeating now after many days. I dont have any bad habits and im on diet now and didnt eat any heavy foods so it doesnt look like GRED or acid reflux . Please help
