Hi. So I ve had a chronic cough for a year, maybe a bit longer. A year ago I was diagnosed with HBP & and had a check-up on it 4 months ago and also for my lymph nodes because they have always been swollen. My doctor changed my medicine (I was on Lisinopril) because she thought that s what was the cause for my coughing. It s been 4 months and my cough still hasn t gone away. She also ordered another blood test. I got the results the next day and they said everything looked good except that my WBC count was a bit high. Also when I squeeze my breasts together, my breastbone feels sore or bruised. Sometimes I ll hear it pop. It also starts to feel that way if I do any physical activity, lift something heavy or exercise, like a push up or something.
