My girlfriend was recently diagnosed with hyperthyroidism after a scan registered an irregularity with her thyroid gland. She has been experiencing chest pains and palpitations, as well ass dizzy spells and fatigue. The doctor who we are seeing recommended thyroid treatment and a further array of tests to see if there are any other possible causes. Over the last 2 weeks her condition has been worsening and the dizziness/chest pain attacks have become very frequent, to the point where she has little energy to get out of bed. She says the entire left side of her body feels like there is extreme pressure on it, and it is focused in her chest. Could this condition be more than just a thyroid problem? The doctor did an EKG and found no irregularity. They did a cat scan of her head and said there was an irregular artery, and that she has sinusitis and that it could be affecting the condition as well. We are currently seeking treatment for her thyroid but her insurance doesn't cover it. What should I do? I cant stand to see her like this and it seems as if its getting worse and worse.
