I was given a thyroid ultrasound three years ago because I was not feeling well and the doctor wanted to rule out a thyroid problem. I was told at that time I had nodules on my thyroid but because my blood tests appeared normal the tests would be repeated periodically unless new symptoms appeared . I did continue to have swallow issues when eating raw vegetables , meats , breads and also horrible insomnia . In April the ultrasound was repeated , however , the results were just given to me . I was told I have a goiter but because my blood tests were still normal nothing would be done . In August I developed a cough which has gotten so bad I sometime experience a bronchial spasm . This cough also produces a clear mucus .My insomnia continues yet I have endless energy though my body sometimes is exhausted . I am 65 years old and all my doctor is doing is prescribing antibiotics for the cough . Are any of these symptoms related or am I just going crazy ?
