i have had i bad cough for about 6 months now and i have been getting bad migranes in the morning nd when im laying down, also very sharp pains in he middle of my left rib cage, and i have been to the doctors 3 times and the first time they gave me antibiotics and the second time they gave me cough syrup and the third time they gave me sinus spray. They have also done chest & sinus xrays and they both h\came back normal they also did pulminary function tests and blood work but they cannot find out what is causeing my cough.... my cough will be very bad and some times it will be a wet cough sometimes a very dry cough, and them it will slow down once in a whle but surley it starts again. I am constantly in pain and just want to find out what is wrong so i can get the proper treatment .... Thank you
