I am convinced my 12 year old daughter has whooping cough (although I could have scared myself with Google), 4 weeks ago she came down with an awful cold, and a mild cough, the second week the cold cleared up and the cough got worse, to the point she was bringing up huge amounts of phlegm. I took her to the doctors and he said he couldn't hear anything on her chest, but give her some antibiotics, then after the third week of coughing so much she was being sick and waking up during the night, I started to Google her symptoms, that is when I started to suspect whooping cough. These coughing fits go on for quite some time and she makes a whoop sound usually in the middle of a coughing fit, like she's trying to catch her breath and then carry's on coughing, we got another appointment with the dr and mentioned that I thought it may be whooping cough, the dr looked at me as though I was mad, and dismissed what I had told him, I said to him that she was whooping but on his report he wrote wheezing, and asked if there was any history of asthma. Later that night after listening to her coughing and gasping for breath, I took her to the emergency doctors for a second opinion, the doctor checked her over and again said she couldn't hear anything on her chest and everything was ok, with her. I am so angry and scared that I can't get anyone to even consider the possibility, as she has been around my grandson who is only 5 weeks old, and although it was before she had any symptoms I would like the reassurance, as he hasn't been vaccinated. I feel totally helpless and just wondered if she does have whooping cough would the doctor be able to hear it in her chest? or would anything be wrong with her oxygen levels? as these are the only things they have checked on her and said that they are fine, but something isn't right with her, as her cough has lasted a month now and is making her sick.
