My boyfriend is having weakness, dizziness, tiredness, and sometimes headaches. He's only 20, keep that in mind! He's searched everything and can't find the problem..He's already gone to the er but not for these conditions, for rapid heart rate and the Dr. Gave him some beta-blocker metoprolol or something like that. And said that he should go to the Dr. And get an holter moniter and a echocardiogram, well I called and tried to make the appointment and the lady said that because he didn't have insurance she wasn't going to make the appointment, because the echo was $700.00 and we had to have the money upfront :( I think that was kindof rude of her, but before we hung up I asked her if there were any another options and she just said no and hung up the phone!!! :shock: this was all about 5 days ago, do you think that these symptoms were caused by the beta blocker or something else? The last time he went to the er they did a check up on his thyroids, glucose, all blood cell counts. He's never had a ct or mri, should he get one? We're not sure! Please help! Also we can't really afford going to the Dr.
