i have bad breathing problems, have been to doctors, have had all kinds of tests run and all kind of scans done,they could not find anything,but still i can hardly breath at times.i give out of breath real easy,seems to inhale ok but does not seem to exhale to good. and i have to clear my throat all the time but nothing wants to come out,sometimes i do it so much it makes my voice hoarse, i can barely talk.do it all through the day and night. dont know what else to do for either problem, have tried everything. i have so many doctors bills now that i cant afford to keep going back to them for i am getting nothing done. hope you can help thanks''
